libvirtio: Mark struct virtio_scsi_req_cmd as packed
The struct contains an uneven amount of bytes, so we should use
the "packed" attribute to avoid padding problems here. So far the
problems did not show up yet since the struct is filled by Forth
code only and QEMU seems to be quite forgiving about the length of
the descriptor, but anyway, let's better be safe than sorry here.
