Generally speaking, as long as a rowset has a version, it can be
considered not to be in a pending state. However, if the rowset was
created through ingesting binlogs, it will have a version but should
still be considered in a pending state because the ingesting txn has not
yet been committed.
This PR updates the condition for determining the pending state. If a
rowset is COMMITTED, the txn should be allowed to roll back even if a
version exists.
