[media] zoran: fix integer overflow in setup_window()
`clipcount' is from userspace and thus needs validation. Otherwise,
a large `clipcount' could overflow the vmalloc() size, leading to
out-of-bounds access.
| setup_window()
| zoran_s_fmt_vid_overlay()
| __video_do_ioctl()
| video_ioctl2()
Use 2048 as the maximum `clipcount'. Also change the corresponding
parameter type to `unsigned int'.
