vfio/ccw: Update trace data for not operational event

Browse Source 
We currently cut a very basic trace whenever the FSM directs
control to the not operational routine.

Convert this to a message, so it's alongside the other configuration
related traces (create, remove, etc.), and record both the event
that brought us here and the current state of the device.
This will provide some better footprints if things go bad.
