io_uring: don't use TIF_NOTIFY_SIGNAL to test for availability of task_work
[ Upstream commit 6434ec0186b80c734aa7a2acf95f75f5c6dd943b ]
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.
