      libxl: Do not trust backend for disk eject vdev
      
      For disk eject, use configured vdev from /libxl, not backend.
      
      The backend directory is writeable by driver domains.  This means that
      a malicious driver domain could cause libxl to see a wrong vdev,
      confusing the user or the toolstack.
      
      Use the vdev from the /libxl space, rather than the backend.
      
      For convenience, we read the vdev from the /libxl space into the evg
      during setup and copy it on each event, rather than reading it afresh
      each time (which would in any case involve generating or saving a copy
      of the relevant /libxl path).
      
      This is part of XSA-178.
