Subject: [PATCH -tip] sched: Use root_task_group_empty only with
	FAIR_GROUP_SCHED

Please review. Perhaps there some usage planned in future?

	-- Cyrill
---
root_task_group_empty is used only with
FAIR_GROUP_SCHED so if we use other scheduler
we get

kernel/sched.c:314: warning: ‘root_task_group_empty’ defined but not used

So move CONFIG_FAIR_GROUP_SCHED up that it cover
root_task_group_empty.
