Prempt the condition to check whether MDT can be rolled back before running rollback in data table

[hudi-bot]

Currently, while restoring, after we have processed N rollbacks in data table (rollbacks are not yet committed), we call metadata writer update method which then checks if there is at least a base file upto the point being restored. If not, then it aborts and the N rollback processing is wasted. The check in metadata writer update can be moved upfront.
