Subject: [PATCH] mm: fix gfp-translate for changes in gfp.h

The commit cb5a065b4ea9 ("headers/deps: mm: Split <linux/gfp_types.h>
out of <linux/gfp.h>") made all the gfp flags that the gfp-translate
script needed to move from gfp.h to gfp_types.h.  Made changes
accordingly in the gfp-translate scipt.
