sgsn: Extract the MSISDN from the subscr data structure
In case there is a subscr attached to the MM context and there
is an encoded MSISDN we will attempt to decode it and in case
of an international number prepend a '+'. Assume that the array
size of gsm_mmcc_called->number is as big as ctx->msisdn for the
strncpy.
