net: macb: write mac address when initialization
When boot up without mac address setting, it will give the warning message like: "Warning: failed to set MAC address", however when execute network related command, it still execute them without any warning information. With this patch, it will exit directly with following information: "gmac0: mac address is not valid" It also solve the problem after bootup then set mac address and the mac address won't set to net device issue.
