It's possible to add a lower position counter through CRON

[eduardomozart]

• Version of the plugin : 1.7.0

• Version of your GLPI : 9.5.2

• Steps to reproduce (which actions have you made) :

The specification documentation has a diagram that shows the error management of the plug-in - https://forge.glpi-project.org/projects/glpi/wiki/SNMP_printer_counters#27-Gestion-des-erreurs

It states that, if the Counter < Last record, the Counter isn't added, but it's possible when adding it through the CRON script.

E.g. The following screenshot:

1. This is an intentionaly added "Manual" record with a higher value than the last ones.
2. The second is an attempt to add a "Manual" record with a lower value than the last one (it fails, as it should).
3. The third is the result of the CRON script: it adds the record even if it's lower than the last one.

• Expected result :

The third result should return an "Record error" instead of "Success".

• Actual result :

The record is written into the database.
