mm/migrate: remove putback_lru_pages, fix comment on putback_movable_pages
Some part of putback_lru_pages() and putback_movable_pages() is
duplicated, so it could confuse us what we should use. We can remove
putback_lru_pages() since it is not really needed now. This makes us
undestand and maintain the code more easily.
And comment on putback_movable_pages() is stale now, so fix it.
