Public bug reported:

When an instance with a volume is shelved (shelved_offloaded), the
availability zone (AZ) of the instance is not correctly handled when
attempting to attach the volume. The bug occurs because the AZ check is
not being performed properly when an instance does not have a pinned
availability zone.

1. I did create volume
$ openstack volume create test_volume --image 73d2c491-9970-476c-9fdf-751a60b07ed1 --size 20 --availability-zone az1

2. I did create instance
$ openstack server create test_instance --network e6addcac-5ea8-427b-94b5-1a9cf6767ad7 --volume test_volume --availability-zone az1 --flavor <some_flavor> 

3. I did shelve instance
$ openstack server shelve test_instance

4. I did create volume for attach
$ openstack volume create attach_volume --size 1 --type <type> --availability-zone az1

5. I did attach volume to shelved_offloaded instance
$ openstack server --os-compute-api-version='2.20' add volume test_instance attach_volume
