net/mlx5: E-Switch, Use vport metadata matching only when mandatory

Browse source

Multi-port RoCE mode requires tagging traffic that passes through the
vport.
This matching can cause performance degradation, therefore disable it
and use the legacy matching on vhca_id and source_port when possible.
