media: v4l2-dev: Add range check for vdev->minor
If the fixed minor ranges are not properly set we could end up in a
situation where the calculated minor is invalid. Add a check for this in
the code to make it more robust.
This check also fixes the following false positive smatch warning:
drivers/media/v4l2-core/v4l2-dev.c:1036 __video_register_device() error: buffer overflow 'video_devices' 256 <= 288
drivers/media/v4l2-core/v4l2-dev.c:1043 __video_register_device() error: buffer overflow 'video_devices' 256 <= 288
drivers/media/v4l2-core/v4l2-dev.c:1101 __video_register_device() error: buffer overflow 'video_devices' 256 <= 288
