[media] gspca_vc032x: Fix wrong bytesperline
I found a problem on vc032x gspca usb webcam subdriver: "bytesperline" property is wrong for YUYV and YVYU formats. With recent v4l-utils library (>=0.9.1), that uses "bytesperline" for pixel format conversion, the result is a wrong jerky image. Patch tested on my laptop (USB webcam Logitech Orbicam 046d:0892).
