Better to fix mjpeg_qsv in a separate patch if mjpeg_qsv is not able to resetany parameter.

[FFmpeg-devel] [PATCH 3/6] libavcodec/qsvenc: Add "slice" intra refresh type to qsvenc

[Wenbin Chen]

Add "slice" intra refresh type to h264_qsv and hevc_qsv. This type means
horizontal refresh by slices without overlapping. Also update the doc.
