rcu: Give different levels of the rcu_node hierarchy distinct lockdep names
Previously, each level of the rcu_node hierarchy had the same
rather unimaginative name: "&rcu_node_class[i]". This makes
lockdep diagnostics involving these lockdep classes less helpful
than would be nice. This patch fixes this by giving each level
of the rcu_node hierarchy a distinct name: "rcu_node_level_0",
"rcu_node_level_1", and so on. This version of the patch
includes improved diagnostics suggested by Josh Triplett and
Peter Zijlstra.
