Get the JsMsgPart which contains the JMF Message described by the
schema for the data field in the JsPayload Schema, if it has already been
fluffed up and cached.
If the part is not already fluffed and cached, just return null as the caller
does NOT want to fluff it up.

@return JsMsgPart The message part for the JsPayload schema's data field, or null
