gpio: Return -ENODEV if gpio_hog_lookup_name() is empty
If CONFIG_GPIO_HOG is not set, then gpio_hog_lookup_name() is empty, and thus does not initialize any of its parameters. It does still return 0 though, and so any calling function might assume that the parameters have been initialized successfully. Change the return value to -ENODEV in this case, as the function would in the case when CONFIG_GPIO_HOG is set but the gpio hog could not be found.
