io_uring: rsrc: delegate VMA file-backed check to GUP
Now that the GUP explicitly checks FOLL_LONGTERM pin_user_pages() for broken file-backed mappings in "mm/gup: disallow FOLL_LONGTERM GUP-nonfast writing to file-backed mappings", there is no need to explicitly check VMAs for this condition, so simply remove this logic from io_uring altogether.
