I think that the current solution is not perfect, ideally we should block the 
async part of query from finishing before ExecuteStatement is finished - the 
current solution is hard to reason about, e.g. what happens of the DDL is 
finished before reaching SetQueryInflight(). Also discussed this with Riza on 
another channel.

As the current state can hide other issues from TSAN, I am ok with merging 
this, but preferably there should be a follow up commit to clean this up.
