Revert "Use group updates when setting transaction status in clog."
This reverts commit ccce90b398673d55b0387b3de66639b1b30d451b. This
optimization is unsafe, at least, of rollbacks and rollbacks to
savepoints, but I'm concerned there may be other problematic cases as
well. Therefore, I've decided to revert this pending further
investigation.
