When enabling L2Announcer and using the sharedingkeys feature, deleting a service that uses the same requestIP will unexpectedly delete the allocated LB IP in the Cilium agent. Fixes: cilium#32115 Signed-off-by: Taizeng Wu <wutaizeng@gmail.com>

When creating multiple services using the same IP, you can still see the IP listed multiple times in the statedb on multiple nodes.
