Before PHP 8.1, the mysqli extension had MYSQLI_REPORT_OFF as default setting.
With PHP 8.1, it has been changed to MYSQLI_REPORT_ERROR|MYSQLI_REPORT_STRICT
The native driver is not ready to work with this new reporting level,
see MDL-75761 about to considering to improve it.
So this change just ensures that we continue using MYSQLI_REPORT_OFF
with any PHP version.
