If the IPA fails during configuration, return an error flag to the pipeline handler and fail the use case gracefully. At present, the IPA configuration can fail for the following reasons: - The sensor is not recognised, and fails to open a CamHelper object. - The pipeline handler did not pass in controls for the ISP and sensor.
