If qemuPrepareHostdevUSBDevices fail it will roll back devices added
to the driver list of used devices. However, if it may fail because
the device is being used already. But then again - with roll back.
Therefore don't try to remove a usb device manually if the function
fail. Although, we want to remove the device if any operation
performed afterwards fail.
