rcu: Mark loads from rcu_state.n_online_cpus
The rcu_state.n_online_cpus value is only ever updated by CPU-hotplug
operations, which are serialized. However, this value is read locklessly.
This commit therefore marks those reads. While in the area, it also
adds ASSERT_EXCLUSIVE_WRITER() calls just in case parallel CPU hotplug
becomes a thing.
