MFC r309851:

Ensure that the reported ppid and tsn are taken from the first fragment.

This fixes a bug where the wrong ppid was reported, if
* I-DATA was used on the first fragement was not received first
* DATA was used and different ppids where used.

Thanks to Julian Cordes for making me aware of the issue.
