lindebugfs: check that name is set as otherwise pfs_alloc_node_flags() panics
I have hit the case multiple times that some LinuxKPI field may not be
set during driver bringup and lindebugfs would cause a panic.
The backtrace goes like:
strlen() at strlen+0x54
pfs_create_dir() at pfs_create_dir+0x41
debugfs_create_dir() at debugfs_create_dir+0xa1
...
While the problem is clearly in LinuxKPI or the driver, we likely
should at least add an assert to pfs_create_dir() if name is NULL
like we have for pfs_add_node() but for lindebugfs at least make
this a graceful error and continue without creating the dir instead
of panicing.

sched_shim: restore kern.ccpu sysctl
It is apparently should be considered part of the ABI, and is used by
the base top(1). But do not declare the ccpu variable in headers, it is
needed only by 4bsd. So put the variable definition into sched_shim.c to
make the kernel buildable without SCHED_4BSD.

x86/local_apic.c: remove direct SCHED_ULE use
Move the code to decide on the timer accounting into the scheduler hook.
Since there were no inclusion of opt_sched.h, it is probably done
unconditionally anyway.
