Sort DeviceIDs in GetPodResourceMap for deterministic ordering

When a namespace uses a primary User-Defined Network (UDN) with a
device-plugin resource (e.g. SR-IOV), OVN-Kubernetes uses the last
device in the list for the primary interface while Multus assigns
earlier devices to cluster-default/secondary interfaces. The kubelet
and checkpoint paths build the list from map iteration, so order was
non-deterministic and the "last" device could differ between callers.
Sorting ensures both Multus and OVN-K8s see the same order so the
last device is consistently the one reserved for the primary UDN.
