   avformat: Restore the container channel layout after a failed decoder open
   avformat_find_stream_info() copies codec parameters from the decoder
   context after probing, including when avcodec_open2() has already
   failed. A failed avcodec_open2() zeroes the context channel layout via
   ff_codec_close() -> av_opt_free(), because ch_layout is an
   AV_OPT_TYPE_CHLAYOUT option. That empty layout is then written back
   onto codecpar and replaces the value the demuxer had already set from
   the container.
   
   This is reachable for codecs such as adpcm_psx that have no parser and
   do not set AVSTREAM_PARSE_*: the only source of the channel count is
   the demuxer header. It differs from codecs like mp3, where the decoder
   is expected to fill the layout.
   
   Restore the container channel layout when it was specified and the
   decoder result is unspecified, matching the existing restore of color
   metadata in parameters_from_context().

   avformat/vpk: Check the channel count before dividing in the last block
   vpk_read_packet() divides last_block_size and block_align by
   codecpar->ch_layout.nb_channels when assembling the last interleaved
   block. Header parsing already rejects a non-positive channel count,
   but a failed avcodec_open2() can later zero the layout through
   ff_codec_close() -> av_opt_free(), so the division is reached with a
   zero divisor.
   
   Check the channel count again before dividing and return
   AVERROR_INVALIDDATA.

   tests/fate: Add a VPK regression test for a zeroed channel layout
   Generate the 21-byte sample from issue #24290 and copy it with
   ffmpeg. avformat_find_stream_info() must keep the container channel
   count at 80 instead of replacing it with 0 after adpcm_psx fails to
   open; the decoder cannot be opened, so ffprobe -show_entries is not
   usable here.
