    Only say we have a new resolved MAC address if it's actually *new*.

    If we aren't changing the resolved name, it's not new.

    This prevents us from perpetually "resolving" the address.  If we have
    ARP packets that cause us to map a MAC address to a host name, based on
    the ARP packet saying the MAC address corresponds to a given resolved IP
    address, then each time we dissect the packet, the address will be
    "resolved" - and each time we have new resolved addresses as a result of
    that, we'll redissect the displayed packets so that they show the
    resolved address, and we'll forever be redissecting.
