net/mlx5e: Check correct ip_version in decapsulation route resolution

Browse Source 
flow_attr->ip_version has the matching that should be done inner/outer.
When working with chains, decapsulation is done on chain0 and next chain
match on outer header which is the original inner which could be ipv4.
So in tunnel route resolution we cannot use that to know which ip version
we are at so save tun_ip_version when parsing the tunnel match and use
that.
