net/mlx5: E-Switch, Use vport metadata matching only when mandatory
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.
Fixes: 92ab1eb392c6 ("net/mlx5: E-Switch, Enable vport metadata matching if firmware supports it")
