Peter Zijlstra 057f3fadb3 sched: Fix sched_domain iterations vs. RCU 
Vladis Kletnieks reported a new RCU debug warning in the scheduler.

Since commit dce840a087 ("sched: Dynamically allocate sched_domain/
sched_group data-structures") the sched_domain trees are protected by
RCU instead of RCU-sched.

This means that we need to include rcu_read_lock() protection when we
iterate them since disabling preemption doesn't suffice anymore.
