Fix errno check based on EINTR in pg_flush_data()

Browse source 
Upon a failure of sync_file_range(), EINTR was checked based on the
returned result of the routine rather than its errno.  sync_file_range()
returns -1 on failure, making the check a no-op, invalidating the retry
attempt in this case.

Oversight in 0d369ac650.
