Only one path will consume the @def; otherwise, we need to free it.

Long term solution should probably be that these consumers make their own copy
so that we don't need to differentiate. As for short term solution, I'd prefer
if we freed def unconditionally and thus resetting @def to NULL before issuing
break; in the _NETFS path, you'd need a def->type helper for that.
