io_uring/msg_ring: check file type before putting
If we're invoked with a fixed file, follow the normal rules of not calling io_fput_file(). Fixed files are permanently registered to the ring, and do not need putting separately. Cc: stable@vger.kernel.org Fixes: aa184e8671f0 ("io_uring: don't attempt to IOPOLL for MSG_RING requests") Signed-off-by: Jens Axboe <axboe@kernel.dk>
