Commit 9f162193d6e4 ("radix-tree: replace gfp.h inclusion with
gfp_types.h") change the include file, which is introduced in
commit cb5a065b4ea9c ("headers/deps: mm: Split <linux/gfp_types.h> out
of <linux/gfp.h>"). Since we don't do the split for test, current build
for radix-tree would fail.

Let's do the same as in commit cb5a065b4ea9c ("headers/deps: mm:
Split <linux/gfp_types.h> out of <linux/gfp.h>").
