avcodec/h264dec: set AVFrame decode_error_flags in case of decoding error

Browse Source 
set AVFrame decode_error_flags in case h->slice_ctx->er.error_occurred is set
after the call to ff_h264_execute_decode_slices. This allows the user to detect
concealed decoding errors in the call to avcodec_receive_frame
