io_uring: don't use TIF_NOTIFY_SIGNAL to test for availability of task_work
Use task_work_pending() as a better test for whether we have task_work or not, TIF_NOTIFY_SIGNAL is only valid if the any of the task_work items had been queued with TWA_SIGNAL as the notification mechanism. Hence task_work_pending() is a more reliable check. Signed-off-by: Jens Axboe <axboe@kernel.dk>
