Fix level control's currentLevel update when receiving an Off command (…

…#20788) According to the Application Clusters specification, when Level Control cluster is used in association with the On/Off cluster, the action on receipt for an Off command should be to change the current level to: * the minimum level allowed for the device, if OnLevel is defined. * the stored level, if OnLevel is not defined. In the current implementation, when receiving an Off command, the currentLevel attribute is always restored to the stored value.
