vfio-pci: preserve MSI
Save the MSI message area as part of vfio-pci vmstate, and preserve the interrupt and notifier eventfd's. migrate_incoming loads the MSI data, then the vfio-pci post_load handler finds the eventfds in CPR state, rebuilds vector data structures, and attaches the interrupts to the new KVM instance.
