passthrough: allow pt_bind_irq for msi update

Extend pt_bind_irq to handle the update of msi guest
vector and flag.

Unbind and rebind using separate hypercalls may not be viable
sometime.
For example, the guest may update MSI address/data on fly without
disabling it first (e.g. change delivery/destination), implement these
updates in such a way may result in interrupt loss.
