mm: use unsigned long constant for page flags

struct page->flags is unsigned long, so when shifting bits we should use
UL suffix to match it.

Found this problem after I added 64-bit CPU specific page flags and
failed to compile the kernel:

  mm/page_alloc.c: In function '__free_one_page':
  mm/page_alloc.c:672:2: error: integer overflow in expression [-Werror=overflow]
