Ignore extra subnet IPs in DHCP agent
When the DHCP agent requests a port from a server, it asks
for fixed IPs from specific subnets. However, if the server
is doing auto ipv6 addressing, it may give it an extra IP
it never asked for. The previous logic was not expecting this
so it would fail to correctly setup the DHCP port.
This patch just ignores any IPs on subnets the DHCP agent
isn't servicing.

I think the test is test_dhcpv6_64_subnets(), but it's definitely in
the class.
logstash found a lot of these, so it's happening pretty frequently.
