xfs: remove SYNC_IOWAIT
We want to wait for all I/O to finish when we do data integrity syncs. So
there is no reason to keep SYNC_WAIT separate from SYNC_IOWAIT. This
causes a little change in behaviour for the ENOSPC flushing code which now
does a second submission and wait of buffered I/O, but that should finish
ASAP as we already did an asynchronous writeout earlier.
