ipv4/ip_gre: set transport header correctly to gre header
ipgre_tunnel_xmit() incorrectly sets transport header to inner payload instead of GRE header. It seems copy-and-pasted from ipip.c. So set transport header to gre header. (In ipip case the transport header is the inner ip header, so that's correct.) Found by inspection. In practice the incorrect transport header doesn't matter because the skb usually is sent to another net_device or socket, so the transport header isn't referenced.
