net/mlx5: LAG, don't print port mapping to debugfs in MPESW mode

Browse Source 
The mapping debugfs file dumps the LAG virtual-to-physical port mapping.
In MPESW mode the LAG does not own that mapping - port selection is
driven by user steering rules, not by the LAG - so the dumped values are
meaningless.

Treat MPESW as if LAG is inactive and don't print anything to the user.
