well, while i've committed the similar change,
i don't think it's that simple.  it isn't MNT_GETARGS specific.

eg. consider updating !MNT_SOFTDEP to MNT_SOFTDEP.
until ffs_mount notices the attempt and prevents it by setting MNT_SOFTDEP,
MNT_SOFTDEP is left cleared.

i think either of the following is needed.
- change VFS_MOUNT as i suggested above.
- don't share mnt_flag between filesystem independent code and
  filesystem code.
