Do for the IPv6 tunnels what the previous patches did for the IPv4 ones.
The situation is the same, with one difference: ip6_tnl_xmit() does not
free the packet itself, it returns an error and the callers do, so the
reason has to travel with it.  Give it an output parameter, and pass it
down through ipxip6_tnl_xmit(), __gre6_xmit() and the three
ip6gre_xmit_*() helpers to the two places that actually drop.

Warning: ../net/ipv6/ip6_tunnel.c:1113 function parameter 'reason' not described in 'ip6_tnl_xmit'
