mm: remove lru type checks from __isolate_lru_page()
After patch "mm: forbid lumpy-reclaim in shrink_active_list()" we can completely remove anon/file and active/inactive lru type filters from __isolate_lru_page(), because isolation for 0-order reclaim always isolates pages from right lru list. And pages-isolation for lumpy shrink_inactive_list() or memory-compaction anyway allowed to isolate pages from all evictable lru lists.
