mm/balloon_compaction: make balloon page compaction callbacks static
Since commit b1123ea6d3b3 ("mm: balloon: use general non-lru movable page feature"), these functions are called via balloon_aops callbacks. They're not called directly outside this file. So make them static and clean up the relevant code.
