Fix a openvswitch compilation error when CONFIG_INET is not set:
=====================================================
In file included from include/net/geneve.h:4:0,
from net/openvswitch/flow_netlink.c:45:
include/net/udp_tunnel.h: In function 'udp_tunnel_handle_offloads':
>> include/net/udp_tunnel.h💯2: error: implicit declaration of function 'iptunnel_handle_offloads' [-Werror=implicit-function-declaration]
>> return iptunnel_handle_offloads(skb, udp_csum, type);
>> ^
>> >> include/net/udp_tunnel.h💯2: warning: return makes pointer from integer without a cast
>> >> cc1: some warnings being treated as errors
