DU: if requested to remove non-existing UE, just ack

Browse Source 
The failure mode observed here was that the CU sent a release command
for a UE that the DU does not know. Given, that the outcome of the
release command (no UE) is equal to the current state (no UE), from
the DU point of view, we can safely ack the command.
