call_rcu() changes to save power may cause slowness. Use the call_rcu_flush() API instead which reverts to the old behavior. We find this via inspection that the RCU callback does a wakeup of a thread. This usually indicates that something is waiting on it. To be safe, let us use call_rcu_flush() here instead.
