    Remove unnecessary complication around xmlParseBalancedChunkMemory.
    
    When I prepared 71c0921b6 et al yesterday, I was thinking that the
    logic involving explicitly freeing the node_list output was still
    needed to dodge leakage bugs in libxml2.  But I was misremembering:
    we introduced that only because with early 2.13.x releases we could
    not trust xmlParseBalancedChunkMemory's result code, so we had to
    look to see if a node list was returned or not.  There's no reason
    to believe that xmlParseBalancedChunkMemory will fail to clean up
    the node list when required, so simplify.  (This essentially
    completes reverting all the non-cosmetic changes in 6082b3d5d.)
