queue2: post error message when pausing task if so appropriate

Browse source 
If a downstream element returns an error while upstream has already
put all data into queue2 (including EOS), upstream will no longer
chain into queue2, so it is up to queue2 to perform some
EOS handling / message posting in such cases.  See #589991.
