KVM: s390: Fix assumption that kvm_set_irq_routing is always run successfully
This fixes the assumption that kvm_set_irq_routing is always run successfully by instead making it equal to the variable r which we use for returning in the function kvm_arch_vm_ioctl instead of making r equal to zero when calling this particular function and incorrectly making the caller of kvm_arch_vm_ioctl think the function has run successfully.
