pgxml_xpath() builds an xpath_workspace before returning it to
callers.  If an ERROR is thrown before the function returns, callers
have not received the workspace pointer yet and cannot run
cleanup_workspace().

Add local error cleanup for the partially built workspace and the
compiled XPath expression.  Also check xmlXPathNewContext() before
dereferencing the returned context.
