[libvirt] [PATCH 3/3] esx: use newer virtualHW version for 5.1+ hosts

[Dawid Zamirski <dzamirski datto com>]

This is because there's a known issue where ESX will refuse to attach
drives bigger than 4TB when virtualHW < 9. Therefore, to avoid that
use the higher virtualHW for hosts that support it.
