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().
