avaudenc: fix audio encoder flushing according to libav docs

Browse source 
* @param[in] frame AVFrame containing the raw audio data to be encoded.
 *                  May be NULL when flushing an encoder that has the
 *                  CODEC_CAP_DELAY capability set.

The AVFrame itself should be null, not the frame.data pointer
