    Avoid recursive scan_local_interfaces operation
    
    When the local networks interfaces changes quickly or when refreshing the
    list of network interfaces there's a risk of recursive calls into
    scan_local_interfaces. The recursive calls are a result of calling
    update_cb to process UI events during function operation which in turn
    again discover a network interface change. This results in strange
    duplicate entries of network interfaces and crashes.
    
    To avoid recursive calls a check is added to stop running the function while
    already updating. This patch is really just a workaround for the problem.
    Ideally some asynchronous operation should be implemented instead to avoid
    the UI update_cb callback alltogether.
