virtio-scsi: prepare migration format for multiqueue
In order to restore requests correctly from a multitude of virtqueues,
we need to store the id of the request queue that each request came
from.
Do this even for single-queue, by storing a hard-coded zero, to
simplify future implementation of multiqueue.
