Christian Borntraeger 48543509f4 s390/mm: use non-quiescing sske for KVM switch to keyed guest ...

commit 3ae11dbcfac906a8c3a480e98660a823130dc16a upstream.

The switch to a keyed guest does not require a classic sske as the other
guest CPUs are not accessing the key before the switch is complete.
By using the NQ SSKE things are faster especially with multiple guests.
