Subject: [PATCH v3 3/3] igb_main: Assign random MAC address instead of fail in case of invalid one

In some cases, when the user uses igb_set_eeprom to modify the MAC
address to be invalid, the igb driver will fail to load. If there is no
network card device, the user must modify it to a valid MAC address by
other means.

Since the MAC address can be modified, then add a random valid MAC address
to replace the invalid MAC address in the driver can be workable, it can
continue to finish the loading, and output the relevant log reminder.
