A commit record has all subtransaction ids and SnapBuildCommitTxn()
already checks if every one has catalog changes before checking the
top transaction's catalog changes. So, no need to record top-sub
transaction relationship to serialized snapshots. If any of the
subtransactions has catalog changes, the commit contains catalog
changes.
