Fix: LAPDm contention resoltion must acknowledge subsequent SABM

After reception of SABM, the network responds with UA and enters the
establised multiframe state. If UA is not received by mobile, the SABM
is transmitted again, and the network must respond with UA again, unless
it is from a different mobile.

Add LAPDm collision test (contention resolution on network side).
