IMPALA-6595: fix crash in NljBuilder::Close()
The bug is that the right child of a blocking join node could be closed
before the builder if an error was encountered when sending a batch to
the sink. This hits a DCHECK because Buffers owned by the sink may still
be accounted against the child node.
Testing:
Added the test that originally triggered the problem. It reproduced the
failure when based on the IMPALA-4835 patch, but I can't reproduce
the failure after rebase onto master.
