mm/compaction: make defer_compaction and compaction_deferred static

Browse Source 
defer_compaction() and compaction_deferred() and compaction_restarting()
in mm/compaction.c won't be used in other files, so make them static, and
remove the declaration in the header file.

Take the chance to fix a typo.
