kmsan: fix a stale comment in kmsan_save_stack_with_flags()

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.
