bts (RLL): DCCH/SAPI0 LAPDm without contention resolution is legal

The diffrence is whether we establish the LAPDm link
* after RACH + IMM.ASS (we must include L3 payload for contention
  resolution required)
* after assignment from one channel to another (we must not include L3
  payload, i.e. no contention resolution)
