don't return RR list on error

Browse Source 
The resolver maybe returned an error code but allocated an RR list. Free
this list now in the resolver instead of depending on the user to free it
even though there was an error.

This API is only library internal, but still it makes more sense like that.

This issue was discovered in CI job [0].
