V4L/DVB: em28xx: rework buffer pointer tracking for offset to start of video
Rework the logic for tracking the amount of data copied to the VBI buffer, to address problem found where the video lines are several bytes shifted to the right (and the leading pixels in the first line rendered are garbage). This would occur because the copy function would advance the pointer when detecting headers, but the caller would not adjust the length actually copied. This work was sponsored by EyeMagnet Limited.
