When dealing with icmp messages, the skb->data points the ip header that triggered the sending of the icmp message. In gre_cisco_err(), the parse_gre_header() is called, and the iptunnel_pull_header() is called to pull the skb at the end of the parse_gre_header(), so the skb->data doesn't point the inner ip header. Unfortunately, the ipgre_err still needs those ip addresses in inner ip header to look up tunnel by ip_tunnel_lookup(). So just use icmp_hdr() to get inner ip header instead of skb->data.
