kvm-irqchip: simplify kvm_irqchip_add_msi_route
Changing the original MSIMessage parameter in kvm_irqchip_add_msi_route into the vector number. Vector index provides more information than the MSIMessage, we can retrieve the MSIMessage using the vector easily. This will avoid fetching MSIMessage every time before adding MSI routes. Meanwhile, the vector info will be used in the coming patches to further enable gsi route update notifications.
