mm/page_alloc: some renames to clarify alloc_flags scopes

It's pretty confusing that:

- The slowpath and fastpath have a totally distinct set of alloc_flags.

- gfp_to_alloc_flags() sounds generic but it only influences the
  slowpath.

Rename some variables to highlight which alloc_flags are
fastpath-specific.  Rename gfp_to_alloc_flags() to highlight that it's
slowpath-specific.

gfp_to_alloc_flags_cma() and gfp_to_alloc_flags_nonblocking() currently
have perfectly harmless names, but to keep the naming consistent also
rename those to the alloc_flags_*() pattern (which already exists for
alloc_flags_nofragment()).
