ofproto-dpif-xlate: Update tunnel neighbor when receive gratuitous ARP.
OVS now just allow the ARP Reply which the destination address is matched
against the known xbridge addresses to update tunnel neighbor. So when OVS
receive the gratuitous ARP from underlay gateway which the source address
and destination address are all gateway IP, tunnel neighbor will not be updated.
Fixes: ba07cf222a0c ("Handle gratuitous ARP requests and replies in tnl_arp_snoop()")
Fixes: 83c2757bd16e ("xlate: Move tnl_neigh_snoop() to terminate_native_tunnel()")
