cgroup: Fixes for v7.0-rc3

Browse source

- Hide PF_EXITING tasks from cgroup.procs to avoid exposing dead tasks
   that haven't been removed yet, fixing a systemd timeout issue on
   PREEMPT_RT.
 
 - Call rebuild_sched_domains() directly in CPU hotplug instead of
   deferring to a workqueue, fixing a race where online/offline CPUs
   could briefly appear in stale sched domains.
