media: docs: vidioc-dqbuf: State all remaining fields are filled by driver

The specification for VIDIOC_DQBUF is slightly ambiguous on what fields
of |struct v4l2_buffer| is filled by the driver.

Reword it so things are clear: the driver fills in all remaining fields
not specified to be filled in by userspace applications.
