igb: Don't give VFs random MAC addresses
If the user has not assigned a MAC address to a VM, then don't give it a
random one. Instead, just give it zeros and let it figure out what to do
with them.

So, for whatever reason we no longer assign a random MAC address when using the
device in a VM (but we do still use one if attached to igbvf in the host). I
expect we'll eventually see this on all the Intel SR-IOV NICs. The solution is
to use the ip command to assign the VF a valid MAC address prior to using it
with KVM. I'll let those who made the change defend it further if they wish.
