kmsan: fix a stale comment in kmsan_save_stack_with_flags()
After commit446ec83805
("mm/page_alloc: use might_alloc()") and commit84172f4bb7
("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.
