FFmpeg/libavcodec/vaapi_encode_vp9.c
Linjie Fu 2b32068916 lavc/vaapi_encode: add FF_CODEC_CAP_INIT_CLEANUP caps for encoders 
ff_vaapi_encode_close() is not enough to free the resources like cbs
if initialization failure happens after codec->configure (except for
vp8/vp9).

We need to call avctx->codec->close() to deallocate, otherwise memory
leak happens.

Add FF_CODEC_CAP_INIT_CLEANUP for vaapi encoders and deallocate the
resources at free_and_end inside avcodec_open2().
