net/mlx5e: Assign a random MAC to any netdev with a zero MAC address

Browse source

mlx5e_set_netdev_dev_addr() falls back to a random MAC only when the
queried address is all-zeros AND the device is not a vport group
manager.  A vport group manager that comes up with a zero MAC is
therefore left with an invalid all-zero address.

The vport_group_manager exception is unnecessary: a zero MAC is always
invalid, regardless of device type. Drop the condition and assign a
random MAC whenever the queried address is zero, so every netdev comes
up with a valid address.
