V4L/DVB (6755): Avoid troubles when using multiple devices
mv_count is a counter used to move the vertical bars. Before this patch, it where a static var. This works fine for just one device. However, when using multiple devices, every device would increment it. This patch moves it to its correct place: struct vivi_dev. So, now, each device has its own data.
