sched: Fix update_curr_rt()
cpu_stopper_thread() migration_cpu_stop() __migrate_task() deactivate_task() dequeue_task() dequeue_task_rq() update_curr_rt() Will call update_curr_rt() on rq->curr, which at that time is rq->stop. The problem is that rq->stop.prio matches an RT prio and thus falsely assumes its a rt_sched_class task.
