Fiona Ebner bac09b093e block-backend: fix edge case in bdrv_next_cleanup() where BDS associated to BB changes 
Same rationale as for commit "block-backend: fix edge case in
bdrv_next() where BDS associated to BB changes". The block graph might
change between the bdrv_next() call and the bdrv_next_cleanup() call,
so it could be that the associated BDS is not the same that was
referenced previously anymore. Instead, rely on bdrv_next() to set
it->bs to the BDS it referenced and unreference that one in any case.
