    uqmi: do not start 464xlat for dual-stack configurations
    
    If dual-stack configuration is in use, and dhcpv6 option is set, do not start
    464xlat sub-interface for dhcpv6 sub-interace , as the configuration already
    provides IPv4 connectivty, be it through single or dual APN configuration.
