If the mac address can not be read from the device registers or the devicetree, a random address is generated, but this was already done from usbnet_probe, so it is not necessary to call eth_hw_addr_random from here again to generate another random address.
Indeed, when reset was also executed from bind, generate another random mac address invalidated the check from usbnet_probe to configure if the assigned mac address for the interface was random or not, because it is comparing with the initial generated random address. Now, with only a reset from open operation, it is just a harmless simplification.
