NVME disk not mounted

When we have NVME disks in VMs we attempt to use them as spank private tmpdir BUT there is an assumption that they are mounted on /mnt/nvme which is not true for all images/flavours that include nvme

mentioned in commit 6f17a9bf

created merge request !516 (closed) to address this issue

This happens at a minimum for image 356ff1ed-5960-4ac2-96a1-0c0198e6a999 (ubuntu 20.04) on flavour qld.64c600g.A100.nvme
