[INET]: Use port unreachable instead of proto for tunnels
This patch changes GRE and SIT to generate port unreachable instead of protocol unreachable errors when we can't find a matching tunnel for a packet. This removes the ambiguity as to whether the error is caused by no tunnel being found or by the lack of support for the given tunnel type.
