[1/9] media: docs: v4l2-controls: fix sentence rendered in a nonsense way

  This sentence renders as:

> Since such compound controls need to expose more information about
> themselves than is possible with ioctls VIDIOC_QUERYCTRL,
> VIDIOC_QUERY_EXT_CTRL and VIDIOC_QUERYMENU the VIDIOC_QUERY_EXT_CTRL
  ^^^^^^^^^^^^^^^^^^^^^                          ^^^^^^^^^^^^^^^^^^^^^
> ioctl was added.

This does not make sense. Fix by providing an explicit link text. This
results in:

> Since such compound controls need to expose more information about
> themselves than is possible with VIDIOC_QUERYCTRL and VIDIOC_QUERYMENU
> the VIDIOC_QUERY_EXT_CTRL ioctl was added.

This should just refer to VIDIOC_QUERYCTRL, not QUERYMENU. So this
becomes: :ref:`VIDIOC_QUERYCTRL <VIDIOC_QUERYCTRL>`

Thanks for your prompt review. v2 on its way with this patch only, since
