Commit 04964ac3 ("avformat/hls: Fix missing streams in some
cases with MPEG TS") caused a regression where subdemuxer streams that
use probing (e.g. dts/eac3/mp2 in mpegts) no longer get probed properly.

This is because the codec parameters from the subdemuxer stream, once
probed, are not passed on to the main stream.

Fix that by updating the codec parameters if the codec id changes.
