IMPALA-12660: TSAN error in ImpalaServer::QueryStateRecord::Init
The new SimultaneousMultipleQueriesOneSession test within
internal-server-test.cc has revealed a data race condition
where the Impala web UI can read TExecRequest in the
QueryDriver while the frontend is updating this object.
Since the fix would require adding locks to the critical
query planning path and the only impact is the UI showing
slightly outdated data, this race condition is being
ignored.
