SGSN: Iu: follow Service Request according to ETSI PMM IDLE exception

The Service Request is not always responded with a Service Accept.
When the UE is in PMM IDLE, a Security Command is equivalent to a
Service Accept.
See 3GPP TS 124 008, 4.7.13.3 Service request procedure accepted by the network.
