Description: s390/cio: verify the driver availability for path_event call
Symptom: If no driver is attached to a device or the driver does not
provide the path_event function, an FCES path-event on this
device could end up in a kernel-panic.
Problem: There can be path-event generated for devices which are not
bound to any drivers. And this is not verified before callback.
Solution: Make sure the driver is available before the callback.
