gtp-link: set IPv6 socket only

GTP driver bails out for IPv4-mapped-IPv6 socket with EADDRNOAVAIL,
to prevent issues with setsockopt IPV6_ADDRFORM.

GTP control plane checks that tunnel family matches the socket family
for this GTP device, ie. there is a 1:1 mapping between the socket
listener and the device which determines the supported IP tunnel header.
