If the host does not respond in time, the initialization fails. However
the usb ether driver will still be registered. This will make
usb_gadget_probe_driver() fail the next time the initialization is
attempted because it cannot find an available UDC.
Fixing this by calling _usb_eth_halt() when the init fails.
