Bug Description

We have a volume and snapshot of this volume with volume type T1, and we retype this volume to a volume type T2. At this time, volume and snapshot have different volume type. And then we delete the snapshot and check quota usage of project and it wrong! When i delete snapshot it subtract quota usage of volume type T2.

Step to reproduce:
- Create volume volume type T1
- Create snapshot of volume
- Retype volume to volume type T2
- Delete snapshot or delete volume with cascade

This fix is different than the other one and both can work together.
In this patch we make the snapshots retype with the volume.

This issue was fixed in the openstack/cinder release candidate.
