    Elevate context for delete volume with no host.

    So in the case of a volume that is placed in error state
    on create and never actually deployed, the cinder.volume.api delete
    call does a short cut call to db.destroy_volume which is fine because
    all we have is a DB entry (scheduler never deployed the volume).

    Unfortunately, this requires admin context, so just add an elevate
    context to the db.destroy_volume call.

    Fixes bug: 1084273
