Currently, picref will be freed by calling av_frame_free(&picref) in
submit_frame() in qsvvpp.c when working in system memory mode,and normally it
is freed in filter_frame() in vf_vpp_qsv.c when working in other modes.
Double free happens when working in system memory mode, remove to
fix the memory issue.

Can be reproduced by applying the system memory patch and qsvdec+vpp:
ffmpeg -init_hw_device qsv=hw -filter_hw_device hw -c:v h264_qsv -i
input.mp4 \
-vf "vpp_qsv=w=960:h=540,format=rgb32" -f null -
