Subject: [PATCH V2 2/2] usb: gadget: u_ether: Don't warn in gether_setup_name_default()

The function gether_setup_name_default() is called by various USB
ethernet gadget drivers. This function always generates the MAC address
for the ethernet gadget device and always prints a warning when
generating the MAC address. Given that these messages are expected, make
these debug prints instead of warnings.

V1 -> V2: Changed print to debug instead of info.
