virtio_scsi: enable VQs early on restore
virtio spec requires drivers to set DRIVER_OK before using VQs. This is set automatically after restore returns, virtio scsi violated this rule on restore by kicking event vq within restore. To fix, call virtio_device_ready before using event queue. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
