Bug Description

When running a controller with one IPv6-only interface and one IPv4-only interface and enabling DHCP on the VLAN associated with the IPv6 interface, it is possible for MAAS to set the nameserver DHCP option with IPv4 addresses from the other interface. This causes dhcpd6 to crash with a misconfiguration error. This can be worked around by explicitly setting nameserver values on the subnet.
