s390/cio: update measurement characteristics

Browse source

[ Upstream commit 9f3d6d7a40 ]

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.
