sched: Remove redundant update_runtime notifier
migration_call() will do all the things that update_runtime() does. So let's remove it. Furthermore, there is potential risk that the current code will catch BUG_ON at line 689 of rt.c when do cpu hotplug while there are realtime threads running because of enabling runtime twice while the rt_runtime may already changed.
