Commit Message

After commit 446ec83805dd ("mm/page_alloc: use might_alloc()") and
commit 84172f4bb752 ("mm/page_alloc: combine __alloc_pages and
__alloc_pages_nodemask"), the comment is no longer accurate.
Flag '__GFP_DIRECT_RECLAIM' is clear enough on its own, so remove the
comment rather than update it.
