bulk-checkin: drop flush_odb_transaction()

Object database transactions can be explicitly flushed via
flush_odb_transaction() without actually completing the transaction.
This makes the provided transactional interface a bit awkward. Now that
there are no longer any flush_odb_transaction() call sites, drop the
function to simplify the interface and further ensure that a transaction
is only finalized when end_odb_transaction() is invoked.
