docs: Update RCU's hotplug requirements with a bit about design
The rcu_barrier() section of the "Hotplug CPU" section discusses
deadlocks, however the description of deadlocks other than those involving
rcu_barrier() is rather incomplete.
This commit therefore continues the section by describing how RCU's
design handles CPU hotplug in a deadlock-free way.
