    Switch DB and driver precommit methods for delete and update

    Deleting network and router assoc calls need to execute precommit and
    postcommit checks. The method deleted the object in the DB before making
    precommit checks.

    With this change it makes precommit checks before deleting the object, which
    allows the drivers to read the DB with the object being present at delete
    precomit time.

    The same change is applied to updates.
