kvm: extend kvm_irqchip_add_msi_route to work on s390
on s390 MSI-X irqs are presented as thin or adapter interrupts for this we have to reorganize the routing entry to contain valid information for the adapter interrupt code on s390. To minimize impact on existing code we introduce an architecture function to fixup the routing entry.
