gprs_gmm: Clarify comment during TLLI assignment
TS 04.64 sec 7.2.1.1 LLGMM-ASSIGN specifies: """ If TLLI Old all 1's and TLLI New all 1's then TLLI Old and TLLI New are assigned, and TLLI New shall be used when (re-)transmitting LLC frames. Both TLLI Old and TLLI New shall be accepted when received from the peer. It shall be treated as a TLLI change according to subclause 8.3.2. """ Change-Id: I3a17715bf2dba7b03c1335ad106307eb4d5f564a
