[Bug 2095211] Re: partitioning crashed with CurtinInstallError: KeyError DEVNAME

[Olivier Gayot]

Tested by manually calling v2_get_path_to_disk() after connecting a
remote NVMe drive using:

$ nvme connect-all --transport tcp --traddr 10.42.0.235 --trsvcid 4420

The function returns properly on questing, but fails on plucky.
