    power: Fix error handling path in wait loops
    
    When checking the session or logind output, we shouldn't silently
    succeed when there's an IOError.
    
    This doesn't have an impact on reading the session log, but all
    the check_for_suspend() tests fail, and check_no_suspend() will
    obviously always succeed.
