Do not use dnsmasq process as nameserver

[Aaron Rosen]

Previously, if one had more than one dhcp port configured on a network
the host booted on this network got a resolv.conf that contains
a nameserver entry for both dhcp-ports. If there is only 1 dhcp port
it would get the dns-server configured as cfg.CONF.dnsmasq_dns_servers.
This patch removes this code that sets the nameserver to be the dhcp-agent
instead of the one configured.

so what if cfg.CONF.dnsmasq_dns_servers not configured?
