Re: [PATCH 07/31] Don't overwrite error message from 'virXPathNodeSet'

'virXPathNodeSet' returns -1 only when 'ctxt' or 'xpath' are NULL or when the 'xpath' string is invalid. Both are programmign errors. It

doesn't make sense for the code to overwrite the error message for anything supposedly more relevant. The majority of calls to 'virXPathNodeSet' already didn't do this, so this patch fixes the rest to prevent it from spreading again.
