mm/compaction.c: add an is_via_compact_memory() helper
Introduce is_via_compact_memory() helper indicating compacting via
/proc/sys/vm/compact_memory to improve readability.
To catch this situation in __compaction_suitable, use order as parameter
directly instead of using struct compact_control.
This patch has no functional changes.
