rcu: BUG: spinlock recursion on CPU#3, trinity-child19/5970

Hi Paul,

I think I've stumbled on another bug that will increase your paranoia levels even further.

I got the following lockup when fuzzing with trinity inside a KVM tools guest, using latest linux-next.

It appears that it was caused by a03d6178 ("rcu: Move RCU grace-period cleanup into kthread"). This issue doesn't reproduce easily though, it took some fuzzing before hitting it.
