io_uring: do not use prio task_work_add in uring_cmd
io_req_task_prio_work_add has a strict assumption that it will only be used with io_req_task_complete. There is a codepath that assumes this is the case and will not even call the completion function if it is hit. For uring_cmd with an arbitrary completion function change the call to the correct non-priority version.
