This patch aimed to avoid problem with uninitialized virtio-blk and virtio-scsi boot devices. Currently, 12 KiB of memory is allocated for each virtio-blk/scsi, so no more than about 10 devices can be initialized. If the device is not initialized, we cannot boot from it. So, if we have more than 10 devices, we can't boot from any of the following (11, 12, etc.). We can initialize only bootable devices, i.e. listed in boot order list, that this patch does.
