413: if (volume['instance_uuid'] or volume['attached_host']):

the instance_uuid and attached_host don't exist in the volume object now. They live inside the volume_attachment list, if any, for the volume.

volume['volume_attachment'] is a list if there are any attachments.

    Hitachi: Fix access to volume instance_uuid

    The instance_uuid and attached_host no longer exists
    in the volume object. It's part of the attachments that
    show up in volume['volume_attachment'].

    This patch now tests to see if there are any volume
    attachments at all via the volume['volume_attachment'] list.
