media: Clarify the meaning of file descriptors in VIDIOC_DQBUF When the application calls VIDIOC_DQBUF with the DMABUF memory type, the v4l2_buffer structure (or v4l2_plane structures) are filled with DMA-buf file descriptors. However, the current documentation does not explain whether those are new file descriptors referring to the same DMA-bufs or just the same integers as passed to VIDIOC_QBUF back in time. Clarify the documentation that it's the latter.
