[RFC PATCH v1 2/2] s390x/kvm: Pass SIGP Stop flags

[Eric Farman]

When building a Stop IRQ to pass to KVM, we should incorporate
the flags if handling the SIGP Stop and Store Status order.
With that, KVM can reject other orders that are submitted for
the same CPU while the operation is fully processed.
