mm: fix testorder interaction between two kswapd patches
Adjusting cc715d99 "mm: vmscan: forcibly scan highmem if there are too many buffer_heads pinning highmem" for -stable reveals that it was slightly wrong once on top of fe2c2a10 "vmscan: reclaim at order 0 when compaction is enabled", which specifically adds testorder for the zone_watermark_ok_safe() test.
