Zhao Zhili 0e338c4114 avcodec/videotoolboxenc: Use BufNode as sourceFrameRefcon 
ExtraSEI is used as the sourceFrameRefcon of VTCompressionSessionEncodeFrame.
It cannot hold other information which is necessary to fix another issue
in the following patch.

This patch also fixed leak of ExtraSEI on the error path of
vtenc_output_callback.
