This function is called in two different places:
- timer callback, which does not take the graph rdlock.
- bdrv_qed_drain_begin(), which is .bdrv_drain_begin()
callback documented as function that does not take the lock.
Since it calls recursive functions that traverse the
graph, we need to protect them with the graph rdlock.
