Subject: [PATCH V3 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. Calling this function will select a random
host and device MAC addresses. A properly working driver should be
silent and not warn the user about default MAC addresses selection.
Given that the MAC addresses are also printed when the function
gether_register_netdev() is called, remove these unnecessary warnings.

Signed-off-by: Jon Hunter <jonathanh@...dia.com>

V3: Updated patch to remove the prints completely.
V2: Changed print to debug instead of info.
