io_uring: correct comment for IORING_SETUP_TASKRUN_FLAG

Sync with a recent liburing fix, which corrects the comment explaining when the IORING_SETUP_TASKRUN_FLAG setup flag is valid to use. May be use with COOP_TASKRUN or DEFER_TASKRUN, not useful without either of this task_work mechanisms being used.
