    libxl: Fix libvirtd crash on domain restore
    
    Commit cc2a3c2a94 missed one case in the libxl driver where virDomainDef
    is returned from libxlDomainSaveImageOpen and a g_steal_pointer is needed.
    Without it, the virDomainDef object is freed and the driver crashes later
    in the restore process when accessing the object.
