s390/vfio-ap: improve reaction to response code 07 from PQAP(AQIC) command
Let's improve the vfio_ap driver's reaction to reception of response code
07 from the PQAP(AQIC) command when enabling interrupts on behalf of a
guest:
* Unregister the guest's ISC before the pages containing the notification
indicator bytes are unpinned.
* Capture the return code from the kvm_s390_gisc_unregister function and
log a DBF warning if it fails.
