    Ensure dnsmasq accept rules are preset at startup.

    Fix bug 1000853.

    This bug reported that after restarting nova-network, the dnsmasq ACCEPT
    iptables rules were no longer present, causing instances to lose their
    IP addresses. This patch updates the restart_dhcp() function in the
    linux_net driver to ensure these rules are present even if dnsmasq was
    already running. Before this was only done when first starting dnsmasq.
