Set correct UE ID in Kenb Refresh Req

Browse Source 
NAS triggered the Kenb Refresh Req always for (hardcoded) UE 0. This
fixes this by setting the correct UE ID.

An effect of this was that the Kenb would always be set for UE 0,
regardless for which UE it was actually intended. This led for integrity
check failures for every UE with ID > 0.
