    Remove unused message from iogrp_data setup

    The iogrp_data is initialized during do_setup loaded.
    The vdisk_count is originally used but later removed.
    In ValueException raised, the variable is no longer required.
    Remove this will give a clearer message when
    ValueException raised.
