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.
