    libxl: Properly cleanup after libxlDomObjFromDomain
    
    Commit id '9ac945078' altered libxlDomObjFromDomain to return
    a locked *and* ref counted object for some specific purposes;
    however, it neglected to alter all the consumers of the helper
    to use virDomainObjEndAPI thus leaving many objects with extra
    ref counts.
