fix an issue in NodeInfo.Clone()

[Huang-Wei]

• 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, pods with hostNetwork are not scheduled correctly #67453 can be triggered.
• As Refactor HostIP predicate algorithm #55910 was introduced in 1.10, this fix needs to back ported to 1.10 and 1.11 release branches.

Release note:

Fix an issue that pods using hostNetwork keep increasing.
