      Steps to reproduce the issue, in a sandbox:

      # Add a switch with a port with a static IP address.
ovn-nbctl ls-add ls
ovn-nbctl lsp-add ls lsp
ovn-nbctl lsp-set-addresses lsp "a2:01:ea:3d:df:4a 10.128.2.2"
# Enable IPAM for the switch but exclude the IP assigned to the existing LSP
ovn-nbctl set logical_switch ls other_config:exclude_ips="10.128.2.2" other_config:subnet="10.128.2.0/24"

      ovn-northd should exclude the IP from the ones that can be dynamically assigned through IPAM but shouldn't complain about duplicates (the IP is not really used anywhere else).  In reality, northd logs:

      2024-08-22T19:39:50.071Z|00012|ipam|WARN|b86ed8fe-061a-4366-9982-af84395872ba: Duplicate IP set: 10.128.2.2

      This has no functional side effects but it does spam the log.
