can: gs_usb: gs_can_close(): don't complain about failed device reset during ndo_stop
When the USB device is unplugged, gs_can_close() (which implements the
struct net_device_ops::ndo_stop callback) is called. In this function
an attempt is made to shut down the USB device with a USB control
message. For disconnected devices this will fail and a warning message
is printed.
Silence the driver by removing the printout of the error message if
the reset command fails.
