Niels de Vos ecd15970de cleanup: rename csiID to driverInstance
The attribute and variable `csiID` ise used for at least two different
things:

 - name of the driver instance, used for journalling metadata
 - objects of the CSIIdentifier struct, composing a volume-handle

By changing the name of the `csiID` attribute for driver instances to
`driverInstance`, any confusion should be prevented.
