Claudio Imbrenda 0a28e06575 KVM: s390: Fix KVM_S390_VCPU_FAULT ioctl ...

A previous commit changed the behaviour of the KVM_S390_VCPU_FAULT
ioctl. The current (wrong) implementation will trigger a guest
addressing exception if the requested address lies outside of a
memslot, unless the VM is UCONTROL.

Restore the previous behaviour by open coding the fault-in logic.
