Way back when I started making changes for Coverity messages my first set were to a bunch of CHECKED_RETURN errors. In particular virAsprintf() had a few callers that Coverity noted didn't check their return (although some did check if the buffer being printed to was NULL or not). It was suggested at the time as a further patch an ATTRIBUTE_RETURN_CHECK should be added to virAsprintf(), see: https://www.redhat.com/archives/libvir-list/2013-January/msg00120.html This patch does that and fixes a few more instances not found by Coverity that failed the check.
