jeff e0e3d6c9e0 - Move the contents of softdep_disk_prewrite into ffs_geom_strategy to fix
two bugs.
 - ffs_disk_prewrite was pulling the vp from the buf and checking for
   COPYONWRITE, when really it wanted the vp from the bufobj that we're
   writing to, which is the devvp.  This lead to us skipping the copy on
   write to all file data, which significantly broke snapshots for the
   last few months.
 - When the SOFTUPDATES option was not included in the kernel config we
   would also skip the copy on write check, which would effectively disable
   snapshots.
 - Remove an invalid mp_fixme().
