sched/fair: Untangle NEXT_BUDDY and pick_next_task()
[ Upstream commit 2a77e4be12cb58bbf774e7c717c8bb80e128b7a4 ]
There are 3 sites using set_next_buddy() and only one is conditional
on NEXT_BUDDY, the other two sites are unconditional; to note:
- yield_to_task()
- cgroup dequeue / pick optimization
However, having NEXT_BUDDY control both the wakeup-preemption and the
picking side of things means its near useless.
