rcu: Add "notrace" to RCU function headers used by ftrace
Both rcu_read_lock_sched_notrace() and rcu_read_unlock_sched_notrace() are used by ftrace, and thus need to be marked "notrace". Unfortunately, my naive assumption that gcc would see the inner "notrace" does not hold. Kudos to Lai Jiangshan for noting this.
