struct compact_control currently converts the gfp mask to a migratetype, but we
need the entire gfp mask in a follow-up patch.
Pass the entire gfp mask as part of struct compact_control.

If we has gfp_mask, we could use gfpflags_to_migratetype from cc->gfp_mask.
What's is your intention?
Can't speak for David but I left it this way as it means
gfpflags_to_migratetype is only called once per compact_zone. Now I
realize my patch 10/10 repeats the call in isolate_migratepages_range so
I'll probably update that as well.
