habanalabs/gaudi: use direct MSI in single mode
Due to FLR scenario when running inside a VM, we must not use indirect MSI because it might cause some issues on VM destroy. In a VM we use single MSI mode in contrary to multi MSI mode which is used in bare-metal. Hence direct MSI should be used in single MSI mode only.
