rcu: Fix thinko, actually initialize full tree
Commit de078d8 ("rcu: Need to update rnp->gpnum if preemptable RCU
is to be reliable") repeatedly and incorrectly initializes the root
rcu_node structure's ->gpnum field rather than initializing the
->gpnum field of each node in the tree. Fix this. Also add an
additional consistency check to catch this in the future.
