V4L/DVB (12406): em28xx: fix: don't do image interlacing on webcams
Due to historical reasons, em28xx driver gets two consecutive frames and fold them into an unique framing, doing interlacing. While this works fine for TV images, this produces two bad effects with webcams: 1) webcam images are progressive. Merging two consecutive images produce interlacing artifacts on the image; 2) since the driver needs to get two frames, it reduces the maximum frame rate by two.
