V4L/DVB (5258): Cafe_ccic: fix compiler warning

Fix the following warning:
drivers/media/video/cafe_ccic.c: In function `cafe_vidioc_reqbufs':
drivers/media/video/cafe_ccic.c:1197: warning: 'ret' might be used uninitialized in this function
Probably not a real bug, but the warning can be avoided easily.
