V4L/DVB (11945): uvcvideo: Don't accept to change the format when buffers are allocated. Setting a new frame format or size will likely change the buffer size required to store a complete video frame. To avoid a buffer overflow, don't allow VIDIOC_S_FMT calls when video buffers are already allocated.
