Nova/Quantum Integration broken due to typo in serializer

[dan wendlandt]

The bug seems to have been introduced by an error in a blanket changeset to switch Nova from using json to jasonutils. During that translation, a "return" statement was dropped, meaning the serializer always returned Null regardless of what data was pushed in. See: https://github.com/openstack/nova/commit/ba76b954e69de56f76f9db5cade1780bc351be67#L5L42

    fixes typo that completely broken Quantum/Nova integration

    bug 1000887

    fixes bug introduced in ba76b954e69de56f76f9db5cade1780bc351be67 that
    prevented the serializer in the Quantum client code from correctly
    serializing request body data. Instead, the serializer always returned
    None, meaning that requests would have no body, causing the Quantum
    server to return a 400.
