Steps to reproduce

1. Run Telegraf with SMART plugin enabled.
2. Observe metrics.

Expected behavior

Telegraf successfully collects SMART metrics from nvme devices.

Actual behavior

When running Telegraf with a config with SMART plugin's Intel extension enabled, Intel specific metrics are not being reported for nvme drive.

Additional info

The output format of nvme-cli (v1.14+) has been changed, and SMART plugin doesn't read properly from it.
