3.5-stable review patch. If anyone has any objections, please let me know.

commit 25099335944a23db75d4916644122c746684e093 upstream.
If a fixed TEI is used, the initial state of the layer 2 statmachine need to be 4 (TEI assigned). This was true only for Point to Point connections, but not for the other fixed TEIs. It was not found before, because usually only the TEI 0 is used as fixed TEI for PtP mode, but if you try X31 packet mode connections with SAPI 16, TEI 1, it did fail.
