mm: huge_memory: Fix build error. 

Certain configurations won't implicitly pull in <linux/pagemap.h> resulting
in the following build error:

  mm/huge_memory.c: In function 'release_pte_page':
  mm/huge_memory.c:1697:2: error: implicit declaration of function 'unlock_page' [-Werror=implicit-function-declaration]
  mm/huge_memory.c: In function '__collapse_huge_page_isolate':
  mm/huge_memory.c:1757:3: error: implicit declaration of function 'trylock_page' [-Werror=implicit-function-declaration]
  cc1: some warnings being treated as errors
