Fix instability with WAL fsync test in stats.sql
A backend using wal_sync_method set to "open_sync" or "open_datasync"
would fail the test checking the WAL sync data in pg_stat_io. These
modes guarantee that a sync is done when WAL is written to disk, and the
data checked by the test is not incremented in this case,
issue_xlog_fsync() doing nothing.
Oversight in commit a051e71e28a1.
