android: post_processor: Drop return value for process()

PostProcessor::process() is invoked by CameraStream class
in case any post-processing is required for the camera stream.
The failure or success is checked via the value returned by
CameraStream::process().

Now that the post-processor notifies about the post-processing
completion operation, we can drop the return value of
PostProcessor::process(). The status of post-processing is passed
to CameraDevice::streamProcessingComplete() by the
PostProcessor::processComplete signal's slot.
