xl: Fix feeding NumVersions & SuccessorModTime to lifecycle (#11462)

After recent refactor where lifecycle started to rely on ObjectInfo to
make decisions, it turned out there are some issues calculating
Successor Modtime and NumVersions, hence the lifecycle is not working as
expected in a versioning bucket in some cases.

This commit fixes the behavior.
