    VMAX driver - Cleanup of Initiator group fails

    When the last volume has been deleted from the Storage
    Group and the Masking View has been deleted and the
    initiator group is no longer in use, the deletion of
    the Initiator group fails. The initiator group is actually
    deleted off the array, but the code is throwing up an
    error when it uses the now deleted initiator group
    name to search for remaining masking views. The
    solution is to check if the initiator group has been
    deleted by common.terminate_connection before searching
    for remaining masking views.
