Peter Zijlstra 2e0199df25 sched/fair: Prepare exit/cleanup paths for delayed_dequeue 
When dequeue_task() is delayed it becomes possible to exit a task (or
cgroup) that is still enqueued. Ensure things are dequeued before
freeing.

Thanks to Valentin for asking the obvious questions and making
switched_from_fair() less weird.
