Stefano pointed that configure or show UDP_ZERO_CSUM6_RX/TX info doesn't
make sense if we haven't enabled CONFIG_IPV6. Fix it by adding
if IS_ENABLED(CONFIG_IPV6) check.

Thanks for fixing this. I would add:
Suggested-by: Stefano Brivio <sbrivio@redhat.com>
Fixes: abe492b4f50c ("geneve: UDP checksum configuration via netlink")
Fixes: fd7eafd02121 ("geneve: fix fill_info when link down")
