waiting sync pass we need to do a blocking acquire and restart.
   Another thread, typically the buf daemon, may have this buf locked and
   if we don't wait we can fail to sync the file.  This lead to a great
   variety of softdep panics because we rely on all dependencies being
   flushed before proceeding in several cases.
