Catch up to FreeBSD non-MPSAFE deorbit

All filesystems must have their own locking now.
We have been MPSAFE for quite some time, but the preprocessor macro
"MPSAFE" has been removed and we must catch up in order to compile.

The MNTK_MPSAFE macro has not yet been removed, but it is toothless
now, so we can preemptively stop using it.
