avcodec_get_hw_frames_parameters(), called by the user from get_format,
is allocating ctx->internal->hwaccel_priv_data. But the hardware
decoding setup may fail on the user side and it may fallback to software
decoding. In that case, ctx->internal->hwaccel_priv_data is still
allocated but not used anymore.
Fixes the following assert:
Assertion p_dst->hwaccel_threadsafe || (!dst->hwaccel &&
!dst->internal->hwaccel_priv_data) failed at src/libavcodec/pthread_frame.c:426
