rcu: Abstract rcu_cleanup_dead_rnp() from rcu_cleanup_dead_cpu()
This commit abstracts rcu_cleanup_dead_rnp() from rcu_cleanup_dead_cpu() in preparation for the rework of RCU priority boosting. This new function will be invoked from rcu_read_unlock_special() in the reworked scheme, which is why rcu_cleanup_dead_rnp() assumes that the leaf rcu_node structure's ->qsmaskinit field has already been updated.
