Fix XSLT processing of documents over 64kb 

https://crrev.com/573558 accidentally reversed the polarity of a test
such that loading of an XML document by the XSLT processor would stop
if a chunk parsed successfully instead of stopping if the chunk failed
to parse.

This CL corrects the break condition.
