Ah, right, I keep forgetting that this started appearing with the op
blocker series because the failure mode is completely different, so it
seems to have been a latent bug somewhere else that was uncovered by it.
If we're sure that the change of the order in bdrv_append() is what
caused the bug to appear, we can just undo that for 2.9, at the cost of
a messed up graph in the error case when bdrv_set_backing_hd() fails
(because we have no way to undo bdrv_replace_node()).
