v4l2: v4l2_camera_proxy: Acquire only one buffer semaphore on VIDIOC_DQBUF
We use a semaphore to atomically keep track of how many buffers are
available for dequeueing. The check for how to acquire the semaphore was
incorrect, leading to a double acquire upon a successful nonblocking
acquire. Fix this.
