Subject: [PATCH V2 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. Rather than removing the print, update the print
to show MAC address that is generated which is similar to other ethernet
drivers.

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