updata: fix fetching max version in remove-update

- When running the remove-update command it would report the max version
available in the manifest. But it is checking the wrong order so that
the latest version is not correctly reported. This is a simple fix for
that. Instead of reading the version, we read the max_version field
so that the max version is correctly captured.
