io_uring/rw: remove dead file == NULL check
Any read/write opcode has needs_file == true, which means that we would've failed the request long before reaching the issue stage if we didn't successfully assign a file. This check has been dead forever, and is really a leftover from generic code. Signed-off-by: Jens Axboe <axboe@kernel.dk>
