Snapshot in-use count not decrement after snapshot is deleted

[terryg2012]

The snapshot in-use count is not decremented after the snapshot has been deleted, thus leading to the following error:

ERROR: SnapshotLimitExceeded: Maximum number of snapshots allowed (10) exceeded

The version of cinder that I am using is:

Yup, we're not doing any quota management on the delete here. Looking at this we should probably improve the quota management for volume_delete as well.

    Snapshot reservation sync calls wrong resource.

    The snapshot reservations code isn't calling the
    correct resource on sync (it's calling volumes). There's
    also some problems with the logic being used on the delete/clean up
    that are fixed here as well.
