"lbaas delete l7 rule & policy" could leave dirty data

In lbaas plugin side, the logic for deleting l7 rule and l7 policy is as follows:
If the l7 rule(or policy) attached to a load balancer, plugin only calls drivers to delete data (without any database operations); otherwise plugin deletes the data in database.

The codes are as follows:
        if l7policy_db.attached_to_loadbalancer():
            driver = self._get_driver_for_loadbalancer(
                context, l7policy_db.listener.loadbalancer_id)
            self._call_driver_operation(context, driver.l7policy.delete,
                                        l7policy_db)
        else:
            self.db.delete_l7policy(context, id)

As a result:

When try to delete the l7 rule(or policy) attached to a load balancer, dirty data will be left in the database.
