    logind: make sure to terminate systemd user on logouts
    
    Currently if the user logs out, the GC may never call user_stop(),
    this will not terminate the systemd user and (sd-pam) of that user.
    
    To fix this, remove the USER_CLOSING state check that is blocking the
    GC from calling user_stop(). Since if user_check_gc() returns false
    this means that all the sessions of the user were removed which will
    make user_get_state() return USER_CLOSING.
    
    Conclusion: that test will never be statisfied.
    
    So we remove the USER_CLOSING check and replace it with a check inside
    user_stop() this way we know that user_stop() has already queued stop
    jobs, no need to redo.
    
    This ensures that the GC will get its two steps correctly as pointed out
    by Lennart:
    http://lists.freedesktop.org/archives/systemd-devel/2014-February/016825.html
    
    Note: this also fixes another bug that prevents creating the user
    private dbus socket which will break communications with the user
    manager.
