mm: compaction: drop redundant watermark check in compaction_zonelist_suitable()
The watermark check in compaction_zonelist_suitable(), called from
should_compact_retry(), is sandwiched between two watermark checks
already: before, there are freelist attempts as part of direct reclaim and
direct compaction; after, there is a last-minute freelist attempt in
__alloc_pages_may_oom().
The check in compaction_zonelist_suitable() isn't necessary. Kill it.
