net/mlx5e: Fix wrong source vport matching on tunnel rule 

When OVS internal port is the vtep device, the first decap
rule is matching on the internal port's vport metadata value
and then changes the metadata to be the uplink's value.

Therefore, following rules on the tunnel, in chain > 0, should
avoid matching on internal port metadata and use the uplink
vport metadata instead.

Select the uplink's metadata value for the source vport match
in case the rule is in chain greater than zero, even if the tunnel
route device is internal port.
