fix nvme smart bug

[ITJamie]

General information

some nvme disks are missing from monitoring

tested on: debian bookworm

Proposed changes

added an override to assume that any device name containing "nvme" is an nvme disk.

Hey @ITJamie
Thanks for your PR.
Could you please share the output of
cat /sys/block/$N/device/device/vendor

I assume in your system, the file is empty?
If so, can you just do a on ls -l /dev/disk/by-id

We need to have this as deterministic as possible. While one might assume that no one would ever call their ATA disks nvme, it would be helpful for us to get some more insights into that specific case.

ls output:

 ls -l /dev/disk/by-id

without this fix in the pr none of these disks show up

there is no device subfolder inside the device folder on these:
