    Fix gate failure

    Commit 6948467b770df68cb96877f3e0e710650ad63fd4 adds WorkerSupportServiceMixin
    in the inheritance chain, which conflicts with NeutronDbPluginV2 and
    CommonDbMixin.
    NeutronDbPluginV2 should not be as super class of DFL3RouterPlugin, so this
    patch just remove it from super class list.
