[AMF] Fix Network Initiated Deregistration 

When UDM issues a SDM Data Change Notification with request to modify
RAT restrictions, AMF would crash when it tried to send a SDM
subscription delete as part of Network Initiated Deregistration.

Function amf_ue_sbi_discover_and_send() changed from returning boolean,
to returning integer (one of OGS_OK/OGS_ERROR/...).
