peel: reject bad queries with EINVALIDSPEC There are some combination of objects and target types which we know cannot be fulfilled. Return EINVALIDSPEC for those to signify that there is a mismatch in the user-provided data and what the object model is capable of satisfying. If we start at a tag and in the course of peeling find out that we cannot reach a particular type, we return EPEEL.
