    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.
