fix an issue in NodeInfo.Clone()
- usedPorts is a map-in-map struct, add fix to ensure it's deep copied
- updated unit test
**What this PR does / why we need it**:
Due to PR "Refactor HostIP predicate algorithm #55910", internal `usedPorts` data structure was changed from "map[string]bool" to "map[string]map[ProtocolPort]struct{}".
However, it breaks behavior of `NodeInfo.Clone()`: in the before, one loop `for k, v := range usedPorts` worked fine because it's a safe assignment, but it's not safe any more for a map-in-map using original code. A similar go playground sample is here: https://play.golang.org/p/puqMN71cmSO.
**Which issue(s) this PR fixes**:
Fixes#67453 (_Might_ also related with #66568)
**Special notes for your reviewer**:
- No matter pod preemption is enabled or disabled, #67453 can be triggered.
- As #55910 was introduced in 1.10, this fix needs to back ported to 1.10 and 1.11 release branches.
**Release note**:
```release-note
Fix an issue that pods using hostNetwork keep increasing.
