xfs: use WRITE_SYNC_PLUG for synchronous writeout

The VM and I/O schedulers now expect us to use WRITE_SYNC_PLUG for
synchronous writeout.  Right now I can't see any changes in performance
numbers with this, but we're getting some beating for not using it,
and the knowledge definitely could help the block code to make better
decisions.
