mod_websocket: Continue to process data already in the buffer after an error occurs Previously any error, or even a normal websocket close frame, would return early, leaving potentially entire frames in the buffer unprocessed and then discarded. This change stops processing new data, but returns an existing processed data up to the point of the error/close.
