ix(4): Sanitize negative error codes
Due to development history FreeBSD driver error codes are reported
the same way as in Linux (as negatives) which is inconsistent
with FreeBSD standard. It may cause unexpected behavior when driver
errors are interpreted by a kernel as syscall handler return values.
This patch converts error codes from negative to positive values for
NVM access functions.

arm64 vfp: eliminate nested critical sections
At two out of three call sites to vfp_restore_state_common(), the caller
must use critical_{enter,exit}() to prevent preemption between its call
to vfp_restore_state_common() and other actions, notably its call to
sve_enable(). So, it is arguably better to make
vfp_restore_state_common()'s caller responsible for performing
critical_{enter,exit}() and simply perform CRITICAL_ASSERT() inside
vfp_restore_state_common().

ufshci: report the highest LUN number in the path inquiry
cpi->max_lun is an inclusive upper bound, but the driver reported the

ufshci: correct the crypto/config register offsets and HCMID fields
The reserved array after CCAP must be 508, but it was 511.
This pushed the config, MCQ config, and ESI registers from 0x300 and
0x380 up to 0x900. None of these registers are used yet, so nothing
broke.
Also fix the HCMID bank index field. The spec places it at bits
[23:16], but it was defined on top of the manufacturer code at [15:0].

ufshci: consolidate the device query submit/poll pattern
The six query helpers duplicated the same submit, error check, poll,

future changes to the query flow are made in one place. This also
unifies the failure log message format.

ufshci: validate the CDB before allocating a request
The CDB pointer and length checks depend only on the CCB, so perform
them before allocating and initializing the request. This avoids a
wasted allocation for invalid CCBs on the I/O path and removes one
request-free error path.

ufshci: pass the queue being destroyed to the cmd descriptor teardown
ufshci_req_sdb_destroy() hardcoded &ctrlr->transfer_req_queue when
destroying command descriptors instead of using its req_queue argument.
No functional change: the branch only runs for the transfer queue, so
the two pointers are always the same today. Using the argument keeps
the function queue-agnostic for when more transfer queues exist (MCQ).

ufshci: return the real errno from SDB queue construction
ufshci_req_sdb_cmd_desc_construct() and ufshci_req_sdb_construct()
returned ENOMEM for every failure, so an EINVAL from bus_dma_tag_create()
was reported as a memory shortage. Capture and return the real errno,
and drop the cmd descriptor construct's now pointless out label.
No functional change: no caller inspects the value beyond propagating
it, so this only improves the diagnostics on an attach failure.

fts: add fts_openat() API
Add fts_openat() as a new entry point for fts(3).
When dirfd is AT_FDCWD the behaviour is identical to fts_open().
Passing a pre-opened directory fd allows fts traversal inside
Capsicum capability mode where path-based operations are not
permitted.
Capability mode users should use fts_parent->fts_dirfd + fts_name with
openat(2) to access files.

fts: fix file descriptor leak in fts_close
fts_build() stores a dup'd file descriptor in each directory
entry's fts_dirfd. When a traversal is abandoned before
completion and fts_close() is called, the cleanup loop freed
each pending entry with free() without first closing its
fts_dirfd, leaking one descriptor per pending directory.
Close fts_dirfd before freeing each entry in the cleanup loop,
matching the handling already applied to the dummy parent entry
after the loop.
Add a regression test that descends a couple of levels, abandons
the traversal, closes, and asserts the open descriptor count is
unchanged.
