virtio-scsi: fix boot prio detection by using correct lun

Commits

  d6bdb85eb0 virtio-scsi: skip initializing non-bootable devices
  f82e82a5ab2 virtio-mmio: add support for scsi devices.

both use the lun value from tmpl_drv, which is always 0, instead of the
correct one passed as a separate parameter. This causes systems where
LUNs other than 0 are set as bootable, but 0 is not, to not boot.
