Subject: [PATCH] avcodec/vda: define av_vda_default_init2 when

on OSX:
../configure --disable-everything --enable-demuxer=hls make
error message: Undefined symbols for architecture x86_64:
"_av_vda_default_init2", referenced from:_videotoolbox_init in
ffmpeg_videotoolbox.o
so add av_vda_default_init2 when CONFIG_H264_VDA_HWACCEL=0
