mm: when migrate_pages returns 0, all pages must have been released
In some cases migrate_pages could return zero while still leaving a few
pages in the pagelist (and some caller wouldn't notice it has to call
putback_lru_pages after commit cf608ac19c9 ("mm: compaction: fix
COMPACTPAGEFAILED counting")).
Add one missing putback_lru_pages not added by commit cf608ac19c95 ("mm:
compaction: fix COMPACTPAGEFAILED counting").
