Public bug reported:

The Big Switch port creation code has logic to detect when a port
creation request fails because it references a non-existent network on
the backend, which indicates that the controllers are out of sync with
Neutron. However, in the ML2 driver, no calls are made to the controller
on port creation because the host ID is not yet present. This results in
the non-existent error message during the port update operation when the
port is bound, which doesn't trigger a sync and instead raises an
exception.
