Abort read() after CameraSource has stopped

Before this change, CameraSource::read() may loop forever if
- setStopTimeUs() is called when there are no pending unprocessed
frames; and
- New frames that arrive after setStopTimeUs() was called have timestamps
greater than what was passed to setStopTimeUs().

This change makes read() return ERROR_END_OF_STREAM in this situation.
