vxlan: fix tos value before xmit
[ Upstream commit 71130f29979c7c7956b040673e6b9d5643003176 ]
Before ip_tunnel_ecn_encap() and udp_tunnel_xmit_skb() we should filter
tos value by RT_TOS() instead of using config tos directly.
vxlan_get_route() would filter the tos to fl4.flowi4_tos but we didn't
return it back, as geneve_get_v4_rt() did. So we have to use RT_TOS()
directly in function ip_tunnel_ecn_encap().
Fixes: 206aaafcd279 ("VXLAN: Use IP Tunnels tunnel ENC encap API")
Fixes: 1400615d64cf ("vxlan: allow setting ipv6 traffic class")
