    libxl/dm_depriv: Fix non-debug build
    
    Apparently older versions of gcc, when building with debug=n, the
    uninitialized variable logic gets confused.  Distros on which a
    non-debug build will fail include:
    - Centos 7
    - Debian Jessie
    - Ubuntu Trusty
    
    It seems to be one particular path confusing the logic; so just set it
    on that path to keep the compiler happy, while still catching other
    potential paths where it might be unset.
