BUG-8618: eliminate SimpleShardDataTreeCohort subclasses

Now that we handle pre-cancommit failures useing reportFailure(),
there is no need to have specialized subclasses for cohorts, as
the initial failure can cleanly be handled via nextFailure.

This also places a guard in reportFailure() so we do not override
a failure once it is set -- which should only happen in the case
of a dead-on-arrival transaction and it timing out in READY state.
