sbus: disable chaining for SetActive and SetInconsistent

Even in the unlikely case when multiple of these methods where
called in parallel, we must treat them as separate calls and
handle them individually to avoid situations like:

- SetInconsistent
- SetActive
- SetInconsistent

Here, if chained, it translates to SetInconsistent -> SetActive, which
is wrong. Therefore we can not chain these signals.
