Kevin Wolf 40365552c2 mirror: Error out when a BDS would get two BBs ... bdrv_replace_in_backing_chain() asserts that not both old and new BlockDdriverState have a BlockBackend attached to them because both would have to end up pointing to the new BDS and we don't support more than one BB per BDS yet. Before we can safely allow references to existing nodes as backing files, we need to make sure that even if a backing file has a BB on it, this doesn't crash qemu. There are probably also some cases with the 'replaces' option set where drive-mirror could fail this assertion today. They are fixed with this error check as well.
