sched: account task_group->nr_cpus_active for all cgroups
Currently nr_cpus_active is only accounted for top-level cgroups,
because container cgroups, which are the only users of this counter,
could only be created under the root cgroup.
Now things have changed, and containers can reside either under the root
or under machine.slice or in any other cgroup depending on the host's
config. So we can't preserve this little optimization anymore. Remove
it.
