net: mvneta: support EPROBE_DEFER when reading MAC address

If nvmem loads after the ethernet driver, mac address assignments will
not take effect. of_get_ethdev_address returns EPROBE_DEFER in such a
case so we need to handle that to avoid eth_hw_addr_random.

Add extra goto section to just free stats as they are allocated right
above.
