Call of volume_utils.notify_about_snapshot_usage failes

[Ilya Tyaptin]

Then we call volume_utils.notify_about_snapshot_usage(context, snapshot, 'update.start') from api failes. It's happens because snapshot in this case is dict, but in cinder.volume.utils._usage_from_snapshot[1] we try to get 'volume' attribute from snapshot.
Exception *** AttributeError: 'dict' object has no attribute 'volume'

Hi Ilay,

Would you mind clarifying the bug description here please? I can't seem to determine what the bug is based on your description here. The notify call appears to be correct (for create/delete snap) and I don't see the trace?

    Fix _usage_from_snapshot in volume.utils

    Now in this function we trying to get snapshot_ref.volume for
    collecting 'availability_zone'. It's invalid because snapshot_ref
    in this function is __dict__. In this patchset there is fix for
    it.
