geneve: Move udp_conf.local_ip6 under CONFIG_IPV6 in geneve_create_sock().

Unlike struct ip_tunnel_key, struct udp_port_cfg does not always
define IPv6 address fields.

  >> drivers/net/geneve.c:778:12: error: no member named 'local_ip6' in 'struct udp_port_cfg'
       778 |                 udp_conf.local_ip6 = info->key.u.ipv6.src;
           |                 ~~~~~~~~ ^

Let's add CONFIG_IPV6 guard in geneve_create_sock().

Fixes: afabbb56a726 ("geneve: Introduce IFLA_GENEVE_LOCAL and IFLA_GENEVE_LOCAL6.")
