OVS-agent: "invalid IP address" in arp spoofing protection

[YAMAMOTO Takashi]

arp spoofing code tries to install flows with arp_spa=ipv6_address and ovs-ofctl correctly complains.

    OVS-agent: Ignore IPv6 addresses for ARP spoofing prevention

    The flow rules to match on ARP headers for spoofing prevention
    fail to install when an IPv6 address is used. These should be
    skipped since the ARP spoofing prevention doesn't apply to IPv6.
