    [DHCP] Don't resync network if same port is alredy in cache

    Sometimes when port is created on dhcp agent's side, it may happend
    that same port is already in network cache.
    Before this patch if port with same IP address was already in cache,
    resync was rescheduled because of duplicate IPs found in cache.

    Now resync will be scheduled only if duplicate IP address belongs to
    port with different MAC address or different id.
