s390/cio: update measurement characteristics
Per channel path measurement characteristics are obtained during channel path registration. However if some properties of a channel path change we don't update the measurement characteristics. Make sure to update the characteristics when we change the properties of a channel path or receive a notification from FW about such a change.
