autofs: rename sx lock description for am_lock
Rename am_lock description from autofslk -> autfsm.
The lock description, autofslk, is used as the description for
autofs_softc->sc_lock, which is used to protect autofs requests and the
like as opposed to am_lock which protects autofs nodes for a given
mount.
This change allows witness to distinguish different lock orders for each
lock.

linuxulator: Add linux_extattr_get_vp() for atomic getxattr
Move the atomic size-probe-and-read logic into a new
linux_extattr_get_vp() function in linux_xattr.c instead of
modifying the generic extattr_get_vp() in vfs_extattr.c.
This keeps Linux-specific getxattr semantics (ERANGE on
too-small buffer, EOPNOTSUPP to ENOATTR mapping)
self-contained within the linuxulator.
The function probes the attribute size and reads the data
under a single vnode lock, preventing a TOCTOU race between
the size probe and data read.

linuxulator: Fix O_PATH file descriptors errno for f*xattr(2)
LTP open13 expects these operations to fail with EBADF, matching
Linux behavior, but FreeBSD currently returns EOPNOTSUPP
for fgetxattr() on an O_PATH fd
Look up Linux fd-based xattr descriptors with getvnode()
and route the operations through shared kern_extattr_*_fp()
helpers so the O_PATH check and the extattr operation use the
same referenced file.
Apply the same EBADF handling to fsetxattr(), fremovexattr(), and
flistxattr() so the xattr paths stay consistent.
