doc: Make checklist.rst note that spinlocks are implied RCU readers
In kernels built with CONFIG_PREEMPT_RT=n, spinlock critical sections
are RCU readers because they disable preemption. However, they are also
RCU readers in CONFIG_PREEMPT_RT=y because in that case the locking
primitives contain rcu_read_lock() and rcu_read_unlock(). Therefore,
upgrade checklist.rst to document this non-obvious case.
While in the area, fix a typo by changing "read-side critical" to
"read-side critical section".
