bridge: mrp: Disable roles before deleting the MRP instance 

When an MRP instance was created, the driver was notified that the
instance is created and then in a different callback about role of the
instance. But when the instance was deleted the driver was notified only
that the MRP instance is deleted and not also that the role is disabled.

This patch make sure that the driver is notified that the role is
changed to disabled before the MRP instance is deleted to have similar
callbacks with the creating of the instance. In this way it would
simplify the logic in the drivers.
