s390/ap: use the common driver-data pointer
The device struct provides a pointer for driver-private data. Use this in the zcrypt drivers (as vfio_ap already does), and then remove the custom pointer from the AP device structs. As really_probe() will always clear the drvdata pointer on error, we no longer have to do so ourselves.
