mm: compaction: remove redundant VM_BUG_ON() in compact_zone()
Patch series "Some small improvements for compaction".
When I did some compaction testing, I found some small room for
improvement as well as some code cleanups.
This patch (of 5):
The compaction_suitable() will never return values other than
COMPACT_SUCCESS, COMPACT_SKIPPED and COMPACT_CONTINUE, so after validation
of COMPACT_SUCCESS and COMPACT_SKIPPED, we will never hit other unexpected
case. Thus remove the redundant VM_BUG_ON() validation for the return
values of compaction_suitable().
