blk-cgroup: delete rcu_read_lock_held() WARN_ON_ONCE()
A previous commit got rid of unnecessary rcu_read_lock() inside the
IRQ disabling queue_lock, but this debug statement was left. It's now
firing since we are indeed not inside a RCU read lock, but we don't
need to be as we're still preempt safe.
Get rid of the check, as we have a lockdep assert for holding the
queue lock right after it anyway.
