  indeo: Bound-check before applying motion compensation

The added checks and one previously added check are replaced by asserts,
the conditions can only be
true when vectors are invalid or there are worse inconsistencies.
We are checking the vectors validity and there should be no
inconsistencies, thus the checks should not be needed.
Also no files are known to cause any anomalies in ffmpeg

  pcm: always use codec->id instead of codec_id

This is not merged as we consistently use codec_id, while libav against what
the comit message might hint at mixes both in the decoder.
Its fine to use either but it should be consistent.
