Minchan Kim 9d502c1c8d mm/compaction: check migrate_pages's return value instead of list_empty()
Many migrate_page's caller check return value instead of list_empy by
cf608ac19c ("mm: compaction: fix COMPACTPAGEFAILED counting").  This patch
makes compaction's migrate_pages consistent with others.  This patch
should not change old behavior.
