mm: avoid warning when COMPACTION is selected 

COMPACTION enables MIGRATION, but MIGRATION spawns a warning if numa or
memhotplug aren't selected.  However MIGRATION doesn't depend on them.  I
guess it's just trying to be strict doing a double check on who's enabling
it, but it doesn't know that compaction also enables MIGRATION.
