Description: GAP_AuthenticationComplete event is received on key node side after connection handover, when Car Node, candidate node is configured to initiate pairing request. This event is not expected to be received in the key node side, since the key node is paired with the Serving node. This issue is not seen when the candidate node is configured to wait for pairing request. The event is received with status 0xB (=SMP_PAIRING_FAILED_DHKEY_CHECK_FAILED).

How to reproduce:

1. Create connection between Car Node1 and Key Node, then pair.
2. Handover connection from Car Node1 (serving node) to Car Node2 (candidate node).
3. GAP_AuthenticationComplete event is received in Key Node side.
