Don't follow next pointer on documents in xmlXPathRunStreamEval

RVTs from libxslt are document nodes which are linked using the 'next'
pointer. These pointers must never be used to navigate the document
tree. Otherwise, random content from other RVTs could be returned
when evaluating XPath expressions.

It's interesting that this seemingly long-standing bug wasn't
discovered earlier. This issue could also cause severe performance
degradation.
