    Validate VV Set exists in 3PAR drivers

    The 3PAR drivers must first create a volume and then add that
    volume to a virtual volume set on the backend for QoS support.
    If that predefined virutal volume set does not exists the
    volume would not be associated with the correct QoS settings.
    This patch will now look to see if the virtaul volume set
    exists and if not will delete the volume and notify the user
    that the VV Set does not exists.
