[PATCH 1/2] network: ignore/don't log errors when unsetting firewalld zone
The most common "error" when trying to unset the firewalld zone of an
interface is for firewalld to tell us that the interface already isn't
in any zone. Since this is what we want, no need to alarm the user by
logging it as an error.
