Interesting ...
This means that the drive supports at most 95 error log entries, but 
smartctl detected 254 (and accidentally read 255).

So this is either another smartctl bug or a drive firmware bug.

Please run:
$ sudo nvme id-ctrl /dev/nvme0
and report the value behind "elpe:" (Error Log Page Entries).

Thanks,
Christian
