sgsn: Put SGSN related subscriber data into separate struct
There will be an increasing number of SGSN related fields per
subscriber. Instead of extending gsm_subscriber accordingly, a single
struct sgsn_subscriber_data object is assigned to it. The talloc
context used to allocated that object is the subscr object itself.
Therefore it will be freed automatically along with the subscr
object.
