ip6tunnel: Fix no default display of ip4ip6 tunnels

"ip -6 tunnel show" displays only ip6ip6 tunnels not ip4ip6 tunnels
 - it should display all irrespective of proto.

This is because the default tunnel proto is initialized to IPPROTO_IPV6 in ip6_tnl_parm_init() which is fine for a 'add' command but not for 'show'. This patch overrides proto with 0 signifying 'mode any' as the default in case of a 'show'.
