gprs_ns2_sns: Fix memory leak when creating ip[46]_local arrays
Prior to this patch, we would unconditionally allocate new memory
for the local SNS IP endpoints. This results in a memory leak
on every SNS-SIZE procedure.
Let's move to talloc_realloc() which recycles any previously allocated
memory.
