rcu: Simplify RCU CPU-hotplug notification
Use the new cpu_notifier() API to simplify RCU's CPU-hotplug
notifiers, collapsing down to a single such notifier.
This makes it trivial to provide the notifier-ordering
guarantee that rcu_barrier() depends on.
Also remove redundant open_softirq() calls from Hierarchical
RCU notifier.
