Peter Zijlstra 49bd21efe7 sched/core: Fix set_user_nice() ...

Almost all scheduler functions update state with the following
pattern:

	if (queued)
		dequeue_task(rq, p, DEQUEUE_SAVE);
	if (running)
		put_prev_task(rq, p);

	/* update state */

	if (queued)
		enqueue_task(rq, p, ENQUEUE_RESTORE);
	if (running)
		set_curr_task(rq, p);

set_user_nice() however misses the running part, cure this.

This was found by asserting we never enqueue 'current'.
