Subject: [PATCH V3 1/2] usb: gadget: u_ether: Improve print in gether_setup_name_default()

The print in in gether_setup_name_default() does not provide any useful
information because a random MAC address will always be generated when
calling this function. Update the print to show MAC address that is
generated which is similar to other ethernet drivers.

Given that the strings 'self' and 'host' are static, we do not need to
pass these strings as arguments.
