HDDS-6879. Bucket layout as null on default layout type

[tanvipenumudy]

What changes were proposed in this pull request?

As per a recent change to add Bucket Layout information while creating bucket: HDDS-6811 (PR #3479), the information is displayed as expected when we pass a parameter for --layout but is displayed as null when we don't pass any.
It should rather print the default bucket layout type and should not rely on the user params.
