libcamera: v4l2_device: Fix control enumeration bug
When enumerating the available V4L2 controls at video device open time set the V4L2_CTRL_FLAG_NEXT_CTRL flag if an unsupported control type is encountered to prevent infinite loops. While at it, downgrade the message reporting the unsupported control type to Debug, as it is not an error worth being reported unconditionally.
