Vdpa now implements the Migratable trait, which allows the device to be added to the DeviceTree and therefore allows live migrating any vDPA device that supports being suspended. Given a vDPA device can't be resumed from a suspended state without having to reset everything, we don't support pause/resume for a vDPA device, as well as snapshot/restore (which requires resume to be supported). In order for the migration to work locally, reusing the same device on the same host machine, the vhost-vdpa handler is dropped after the snapshot has been performed, which allows the destination VM to open the device without any conflict about the device being busy.
