fix CM Re-Establishment Request: allocate new A conn

For a call re-establishment, the MS shows up on a different cell and
requests CM Re-Establishment (3GPP TS 24.008 9.2.4). As soon as the
Layer 3 is established, the MSC will clear the first A-connection; the
re-establishment *has* to happen on a new separate A-connection. So for
a brief moment we must allow two distinct A-interface connections to be
used for the same subscriber.

Tested by BSC_Tests.TC_cm_reestablishment
added in I1e7d446644f46b8a0a94688e618ffb4f23a8900e
