avcodec/decode: clean-up if get_hw_frames_parameters fails Fixes the following assert: [00007f1df83d17e0] vaapi generic error: avcodec_get_hw_frames_parameters failed: -22 Assertion p_dst->hwaccel_threadsafe || (!dst->hwaccel && !dst->internal->hwaccel_priv_data) failed at libavcodec/pthread_frame.c:349 Reproduced from VLC with VAAPI, when fallbacking from hw to sw.
