Daemon may miss deletion of this object and therefore not
handle any cleanup operations that needs to be performed.

Wait for daemon to consume deletion update and only then
allow this object to be deleted.

If the daemon is restarted, we start not knowing about any
of the managed interfaces. If we perform activities like
reseting everything due to IngressNodeFirewallNodeState
deletion for example, we will not cleanup all XDP programs.
IngNodeFwController knows all pinned interfaces and ensure
we know about them in ebpfSingleton.

Future work is needed to refactor this to not have two
seperate sources of information about the same thing.
