[AMF/SEC] Avoid AMF crash on late SBI client events by removing ran_ue_find_by_id assertions (#3979)

Browse Source 
In certain race conditions, the AMF could receive an SBI response
after the RAN UE context has already been removed.

The ran_ue_find_by_id assertions in
both amf_npcf_am_policy_control_build_create and
amf_nsmf_pdusession_build_create_sm_context would
trigger a fatal abort.

This change removes those assertions so that late SBI client events are
safely ignored and do not crash the AMF.
