Apply patch #76256 from Roman I Khimov to use crop factor from camera, not from lens data.
Lens crop factor in DB only tells us which crop factor was used for lens calibration data, but it has nothing to do with shots made on random user's camera. So the default behaviour should be to use camera's crop factor and only fallback to lens data if there in no data present for camera. As "this should not happen" it's appropriate to spit out some debug message in this case.
