test: simplify error handling in interactive-evdev

Passing -errno around and having separate labels depending on failure types is
superfluous here. All the unref calls can handle NULL and nothing cares about
errno once we're out of the immediate scope. So let's simplify this and deal
with 0 and 1 only.
