io_uring: always wait for sqd exited when stopping SQPOLL thread We have a tiny race where io_put_sq_data() calls io_sq_thead_stop() and finds the thread gone, but the thread has indeed not fully exited or called complete() yet. Close it up by always having io_sq_thread_stop() wait on completion of the exit event. Signed-off-by: Jens Axboe <axboe@kernel.dk>
