This is weird.. I can't replicate the problem at all. I have just copied
your file in the textfile directory, and I get no errors.

$ sudo cp smartmon.prom /var/lib/prometheus/node-exporter/

$ curl -s http://localhost:9100/metrics|grep
smartmon_end_to_end_error_threshold
# HELP smartmon_end_to_end_error_threshold SMART metric
end_to_end_error_threshold
# TYPE smartmon_end_to_end_error_threshold gauge
smartmon_end_to_end_error_threshold{disk="/dev/sdb",smart_id="184",type="sat"}
0

$ journalctl -u prometheus-node-exporter.service |tail -n1
