FBSD: Remove MA_* abstractions
In FBSD/osi_vnops.c, we have a few abstractions (e.g. MA_VOP_UNLOCK)
that used to expand to different things for older FreeBSD versions.
Currently, they always expand to the same thing, so just remove the
abstractions.
While we are changing these calls, also change one instance of
MA_VOP_LOCK to vn_lock (instead of VOP_LOCK), since we're not usually
supposed to call VOP_LOCK directly, according to the VOP_LOCK(9)
manpage. The MA_VOP_LOCK call was added in commit
bd707fb7
(freebsd-almost-working-client-
20020216), seemingly by mistake.
