fix: consider config reset successful after reboot

If configuration reset was applied (nvConfigUpdateRequired == false) and reboot has happened (uptime > sinceStatusUpdate),
there might still be discrepancies in the mlxconfig query that might lead to a boot loop.
In this case, consider the reset successful
