k8s: Fix wireguard with IPAM != ClusterPool
k8s: Fix wireguard with IPAM != ClusterPool

This removes a leftover if-condition from earlier versions of wireguard
in Cilium where it needed to wait for the operator to allocate a
Wireguard tunnel IP (see #15565 for details).

This fixes a bug where Cilium agent would indefinitely wait for K8s node
information when using Wireguard in combination with an IPAM mode other
than ClusterPool.

Fixes: 0ecab37c49a3 ("wireguard: Remove operator")
