avutil/hwcontext_d3d11va: pass the format value from outside for staging texture 

In d3d11va_create_staging_texture(), during the hwmap process, the
ctx->internal->priv is not initialized, resulting in the
texDesc.Format not initialized. Now pass the format value from
d3d11va_transfer_data() to fix it.

$ ffmpeg.exe -y -hwaccel qsv -init_hw_device d3d11va=d3d11 \
-init_hw_device qsv=qsv@d3d11 -c:v h264_qsv \
-i input.h264 -vf "hwmap=derive_device=d3d11va,format=d3d11,hwdownload,format=nv12" \
-f null -
