When trying to set MAC address of an ethethet 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 BluueField), 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.
Fixes: 0d1d73170820 ("net/mlx5: set VF MAC address from host")

'priv->representor' is 1 bit size bitfield (unsigned int representor:1), what is
the point of additional ">=0" check?
Can it be "representor_id >= 0" by any chance?
