Tetsuo Handa f0cc749254 cgroup,freezer: hold cpu_hotplug_lock before freezer_mutex in freezer_css_{online,offline}()
syzbot is again reporting circular locking dependency between
cpu_hotplug_lock and freezer_mutex. Do like what we did with
commit 57dcd64c7e ("cgroup,freezer: hold cpu_hotplug_lock
before freezer_mutex").
