Change subject: IMPALA-7396: unblock testing with 
--thread_creation_fault_injection
......................................................................


Patch Set 1:

There were at least two layers:
1. The Coordinator was not in a terminal state, so it DCHECKed in the 
destructor.
2. I tried a few things to avoid that, including disabling the DCHECK and 
cancelling the query, but I still ended up hitting various lifecycle issues, 
e.g. backend_exec_complete_barrier_ was NULL.
