mm: rename allocflags_to_migratetype for clarity
The page allocator has gfp flags (like __GFP_WAIT) and alloc flags (like
ALLOC_CPUSET) that have separate semantics.
The function allocflags_to_migratetype() actually takes gfp flags, not
alloc flags, and returns a migratetype. Rename it to
gfpflags_to_migratetype().
