net/mlx5: fix VF MAC address set over BlueField

When trying to set MAC address of an ethernet device and if it was
a representor, PMD sets the MAC over the corresponding VF instead.

For the case of HPF (Host PF representor on BlueField), PMD shouldn't
attempt to set it, since it doesn't have any corresponding VF and fails.

This will fix the issue by setting the MAC on the dev directly.
