mm: return boolean from page_is_file_cache()
page_is_file_cache() has been used for both boolean checks and LRU arithmetic, which was always a bit weird. Now that page_lru_base_type() exists for LRU arithmetic, make page_is_file_cache() a real predicate function and adjust the boolean-using callsites to drop those pesky double negations.
