Fix DiskUsageTests NodeStats constructor call

[cwperks]

Description

Fixes a compile failure in DiskUsageTests caused by the test helper using an outdated NodeStats constructor argument list.

Breaking change was #21637

Break can be seen in https://github.com/opensearch-project/OpenSearch/actions/runs/26195056157/job/77072446112

NodeStats now accepts AnalyticsBackendNativeMemoryStats as the final constructor argument. The makeNodeStatsWithResourceUsage helper in DiskUsageTests was missing that trailing argument, which caused CodeQL autobuild to fail during test compilation.

This change adds the missing null argument so the helper matches the current constructor signature.
