KVM: s390: ucontrol: disable in-kernel handling of SIE intercepts
This patch disables in-kernel handling of SIE intercepts for user controlled virtual machines. All intercepts are passed to userspace via KVM_EXIT_SIE exit reason just like SIE intercepts that cannot be handled in-kernel for regular KVM guests.
