gprs: Don't create a subscr entry on InsertSubscriberData

Currently gprs_subscr_rx_gsup_message creates a subscriber entry if
such an entry doesn't exist for the IMSI within an
InsertSubscriberData GSUP message. This behaviour is not compliant to
GSM 09.02, 20.3.3.2 (Subscriber data management/SGSN) where it is
defined, that an error ("Unidentified subscriber") shall be returned.

This patch removes the case distinction, so that an existing
subscriber entry is required for all incoming GSUP messages.
