When the device is disconnected we get the following messages showing
failed operations:
Nov 28 20:22:11 localhost kernel: usb 2-3: USB disconnect, device number 2
Nov 28 20:22:11 localhost kernel: ax88179_178a 2-3:1.0 enp2s0u3: unregister 'ax88179_178a' usb-0000:02:00.0-3, ASIX AX88179 USB 3.0 Gigabit Ethernet

The reason is that although the device is detached, normal stop and
unbind operations are commanded from the driver. These operations are
not necessary in this situation, so avoid these logs when the device is
detached if the result of the operation is -ENODEV and if the new flag
informing about the disconnecting status is enabled.
