[PATCH RFC 01/37] mm: page_alloc: Rename gfp_to_alloc_flags_cma -> gfp_to_alloc_flags_fast

[Alexandru Elisei]

gfp_to_alloc_flags_cma() is called on the fast path of the page allocator
and all it does is set the ALLOC_CMA flag if all the conditions are met for
the allocation to be satisfied from the MIGRATE_CMA list. Rename it to be
more generic, as it will soon have to handle another another flag.
