libavutil/hwcontext_opencl: fix a bug for mapping qsv frame to opencl
mfxHDLPair was added to qsv, so modify qsv->opencl map function as well.
Now the following commandline works:
ffmpeg -v verbose -init_hw_device vaapi=va:/dev/dri/renderD128 \
-init_hw_device qsv=qs@va -init_hw_device opencl=ocl@va -filter_hw_device ocl \
-hwaccel qsv -hwaccel_output_format qsv -hwaccel_device qs -c:v h264_qsv \
-i input.264 -vf "hwmap=derive_device=opencl,format=opencl,avgblur_opencl, \
hwmap=derive_device=qsv:reverse=1:extra_hw_frames=32,format=qsv" \
-c:v h264_qsv output.264
