[BUG] vcsim: criteria does not work in FetchDVPorts

[Syuparn]

Describe the bug
When FetchDVPorts is requested to vcsim, criteria field is ignored and all ports are responded

To Reproduce
Steps to reproduce the behavior:

1. Start vcsim
2. Request FetchDVPorts with criteria as below

var vCenterURL = "https://user:pass@127.0.0.1:8989/sdk"

func main() {
	ctx := context.TODO()
	url, _ := url.Parse(vCenterURL)

	c, _ := govmomi.NewClient(ctx, url, true)
	f := find.NewFinder(c.Client)
	n, _ := f.Network(ctx, "/DC0/network/DVS0")

	dvs := object.NewDistributedVirtualSwitch(c.Client, n.Reference())

	criteria := &types.DistributedVirtualSwitchPortCriteria{
		PortgroupKey: []string{"dvportgroup-11"},
		Inside:       types.NewBool(true),
	}
	ports, err := dvs.FetchDVPorts(ctx, criteria)
	if err != nil {
		fmt.Printf("%+v\n", err)
		return
	}

	for _, port := range ports {
		fmt.Printf("key: %s, portgroupKey: %s\n", port.Key, port.PortgroupKey)
	}
}

Expected behavior
A clear and concise description of what you expected to happen.

• vcsim responds only ports that belong to portgroups specified in the criteria

> go run main.go
key: 0, portgroupKey: dvportgroup-11

Affected version
Please provide details on the version used, e.g. release tag, commit, module version, etc.

• vcsim 0.27.2

Screenshots/Debug Output
If applicable, add screenshots or debug output to help explain your problem.

• vcsim responds all ports in the DVS

> go run main.go
key: dvportgroup-11, portgroupKey:
key: dvportgroup-13, portgroupKey:

Additional context
Add any other context about the problem here.

• In addition to the criteria issue, portgroupKey and portKey seems to be misplaced (as reported in [BUG] vcsim: portgroupKey and key in DistributedVirtualPorts are mistaken #2726).
