From: "Paul E. McKenney" <paulmck@linux.vnet.ibm.com>
Given that the combination of PREEMPT_RCU and HOTPLUG_CPU is producing the most bugs lately, this commit swaps the TREE03 and TREE04 rcu_node-tree geometries so that the test exercising PREEMPT_RCU and HOTPLUG_CPU has three-level rather than two-level rcu_node trees.
