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.
