[media] doc-rst: use the right markup for footnotes

According with ReST spec, footnotes should be like:
[#name], and not [name]. So, change them.

    Random enqueue order permits applications processing images out of
    order (such as video codecs) to return buffers earlier, reducing the
    probability of data loss. Random fill order allows drivers to reuse
    buffers on a LIFO-basis, taking advantage of caches holding
    scatter-gather lists and the like.

    At the driver level :ref:`select() <func-select>` and :ref:`poll() <func-poll>` are
