gre: Don't accidentally set RTO_ONLINK in gre_fill_metadata_dst()
commit f7716b318568b22fbf0e3be99279a979e217cf71 upstream.
Mask the ECN bits before initialising ->flowi4_tos. The tunnel key may
have the last ECN bit set, which will interfere with the route lookup
process as ip_route_output_key_hash() interpretes this bit specially
(to restrict the route scope).
Found by code inspection, compile tested only.
Fixes: 962924fa2b7a ("ip_gre: Refactor collect metatdata mode tunnel xmit to ip_md_tunnel_xmit")
