Public bug reported:

Description
===========
Attempts to cleanup a volume backed instance resize leaves behind the instance directory and additional disk files. This seems to relate to the following change and the additional imagebackend calls made in _cleanup_resize :

    libvirt: Fix/implement revert-resize for RBD-backed images
    https://review.openstack.org/#/c/228505/


Steps to reproduce
==================
* Create a volume backed instance.
* Shutdown the instance.
* resize/migrate the instance to another host.
* Review the instance directory on the source host.

Expected result
===============
The instance directory on the source host is removed.

Actual result
=============
The instance directory on the source host remains and is also populated with a previously unused `disk` file and disk.info file.

Environment
===========
1. Exact version of OpenStack you are running. See the following

# git rev-parse HEAD
6e2e1dc912199e057e5c3a5e07d39f26cbbbdd5b

2. Which hypervisor did you use?
   libvirt + kvm

2. Which storage type did you use?
   (For example: Ceph, LVM, GPFS, ...)
   LVM/iSCSI

3. Which networking type did you use?
   N/A
