v4l2: v4l2_camera_proxy: Clear internal buffer vector on reqbufs 0
If VIDIOC_REQBUFS with count = 0 is called when the stream is not on, clear the proxy's internal vector of buffer. If the stream is on when reqbufs 0 is called, return -EBUSY. Note that this is contrary to what the V4L2 docs say (reqbufs 0 when streaming should also streamoff), but it is how the V4L2 implementation works. v4l2-compliance doesn't seem to care either way, however, so we cater to the implementation, and no longer call streamoff on reqbufs 0.
