net/mlx4_core: Don't give VFs MAC addresses which are derived from the PF MAC
If the user has not assigned a MAC address to a VM, then don't give it MAC which
is based on the PF one. The current derivation scheme is wrong and leads to VM
MAC collisions when the number of cards/hypervisors becomes big enough.
Instead, just give it zeros and let them figure out what to do with that.
