media: iris: Send dummy buffer address for all codecs during drain

Firmware can handle a dummy address for buffers with the EOS flag. To
ensure consistent behavior across all codecs, update the drain
command to always send a dummy buffer address.

This makes the drain handling uniform and avoids any codec specific
assumptions.
