rcu: Prevent soft-lockup complaints about no-CBs CPUs The wait_event() at the head of the rcu_nocb_kthread() can result in soft-lockup complaints if the CPU in question does not register RCU callbacks for an extended period. This commit therefore changes the wait_event() to a wait_event_interruptible().
