net/mlx5: SD, expend vport metadata for SD secondary devices

In Socket Direct configurations the primary and secondary PFs share the
same native_port_num. The eswitch vport metadata encodes pf_num in its
upper bits to distinguish vports across PFs. Without SD-awareness, both
PFs generate identical metadata, causing FDB rules to steer traffic to
the wrong representor.

Add mlx5_sd_pf_num_get() which remaps the pf_num for SD devices.
Use it so each PF in an SD group produces unique vport metadata.
