 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.
