fix: send SNDCP XID only on GERAN Gb contexts
Add a condition for GERAN Gb. SNDCP and IuPS were developed on separate branches, and the merge results in code trying to use an llme on a UTRAN Iu context where the llme is NULL, leading to stack corruption upon PDP ctx act. Change-Id: Ibb20d738c1b64d36630ce8eceb54c33ba4f1b003
