sched: Check the right ->nr_running in yield_task_fair()
With CONFIG_FAIR_GROUP_SCHED, each task_group has its own cfs_rq.
Yielding to a task from another cfs_rq may be worthwhile, since
a process calling yield typically cannot use the CPU right now.
Therefor, we want to check the per-cpu nr_running, not the
cgroup local one.
