Commit 35ce7f29a44a (rcu: Create rcuo kthreads only for onlined CPUs) contains checks for the case where CPUs are brought online out of order, re-wiring the rcuo leader-follower relationships as needed. Unfortunately, this rewiring was broken. This apparently went undetected due to the tendency of systems to bring CPUs online in order. This commit nevertheless fixes the rewiring.
