gprs: Fix retry of ATTACH REQUEST from mobile 

If, for some reason, the mobile did not receive an ATTACH ACCEPT
it resends an ATTACH REQUEST.  The SGSN then would send a new
ATTACH ACCEPT.  However, after sending the new ATTACH REQUEST, it
was unable to find the GMM context if the mobile uses the old
foreign tlli (as it is allowed to do).  This fixes that.
