    Remove the code against flushing public bridge

    As unstack.sh does destroy all bridges, we don't have to refresh bridge
    interface any more, as what is done in commit
    c2dc95add6e46829f1705041c1d9dddab9b360d3. So in this commit we will continue to
    remove the related statements in lib/neutron-legacy. These statements will also
    cause undefined PUBLIC_BRIDGE error.
