Janosch Frank 1ed576a20c KVM: s390: pv: Mark mm as protected after the set secure parameters and improve cleanup
We can only have protected guest pages after a successful set secure
parameters call as only then the UV allows imports and unpacks.

By moving the test we can now also check for it in s390_reset_acc()
and do an early return if it is 0.
