sunxi: Ensure that the NIC specific bytes of the mac are not all 0
On 2 of my H3 boards bytes 13-15 of the SID are all 0 leading to
the NIC specific bytes of the mac all being 0, which leads to the
boards not getting an ipv6 address from the dhcp server.
This commits adds a check to ensure this does not happen.
