Pass correct port data to extension manager
Pass correct port data to extension manager

The CRUD methods in the ML2 plugin must pass the data in the request
body to the extension manager, so it can be processed by all the ML2
extensions enabled in the deployment. The create_port_bulk method is
instead passing the dictionary generated after adding the port to the
DB. This will cause that fields in the request body intended for
extensions will not be processed.
