   Scans all the CRTCs and planes in <em class="parameter"><code>dev</code></em>'s mode_config.  If they're
   using <em class="parameter"><code>fb</code></em>, removes it, setting it to NULL. Then drops the reference to the
   passed-in framebuffer. Might take the modeset locks.
   </p><p>

   Note that this function optimizes the cleanup away if the caller holds the
   last reference to the framebuffer. It is also guaranteed to not take the
   modeset locks in this case.
