  Log:
  Fix a race between the syncer and umount.  When you umount a softupdates
  filesystem softdep_process_worklist() is called in a loop until it indicates
  that no dependancies remain, but the determination of that fact depends on
  there only being one softdep_process_worklist() instance running.  It was
  possible for the syncer to also be running softdep_process_worklist()
  and the pre-existing checks in the code to prevent this were not sufficient
  to prevent the race.  This patch solves the problem.
