rcu: Move lock_class_key to local scope
Currently, the rcu_node_class[], rcu_fqs_class[], and rcu_exp_class[] arrays needlessly pollute the global namespace within tree.c. This commit therefore converts them to static local variables within rcu_init_one(). Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
