Public bug reported:
Description of problem:
An attached encrypted (Barbican) RBD Cinder volume was attached to instance,
write data to it.
Then volume was detached, when trying to reattach the volume to same instance
volume fails to attach. Odd errors on attached nova-compute.log

How reproducible:
Unsure looks like every time I try to re-attach.
Steps to Reproduce:
1. Boot an instance
2. Create an encrypted(Barbican) backed Cinder(RBD) volume, attach to instance
write data.
3. Detach volume from instance
4. Try to reattach same volume to same instance.
$nova volume-attach 923c5318-8502-4f85-a215-78afc4fd641b

5. Volume fails to attach
No error volume remains unattached
