s390/dasd: Process FCES path event notification
If the Fibre Channel Endpoint-Security status of a path changes, a
corresponding path event is received from the CIO layer.
Process this event by re-reading the FCES information.
As the information is retrieved for all paths on a single CU in one
call, the internal status can also be updated for all paths and no
processing per path is necessary.
