blkcg: Drop unnecessary RCU read [un]locks from blkg_conf_prep/finish()
Now that all RCU flavors have been combined either holding a spin lock,
disabling irq or disabling preemption implies RCU read lock, so there's no
need to use rcu_read_[un]lock() explicitly while holding queue_lock. This
shouldn't cause any behavior changes.
v2: Description updated. Leave __acquires/release on queue_lock alone.
