sched,cgroup: Fix up task_groups list
commit 35cf4e50b16331def6cfcbee11e49270b6db07f5 upstream.
With multiple instances of task_groups, for_each_rt_rq() is a noop,
no task groups having been added to the rt.c list instance. This
renders __enable/disable_runtime() and print_rt_stats() noop, the
user (non) visible effect being that rt task groups are missing in
/proc/sched_debug.
