MakeDeviceName creates a unique short device name from the base device name ("memory", "hugepages-2m") We use a random part because the device name is not really that relevant, as long as it's unique. We can very much construct it concatenating nodeName and NUMAZoneID, that would be unique and equally valid as we expose plenty of low-level details like the NUMAZoneID anyway, but the concern is that we would need more validation, e.g, translating the nodeName (dots->dashes) and so on. Since users are expected to select memory devices by attribute and not by name, we just use a random suffix for the time being and move on.
