In my opinion you should try to recreate your csrf token each request

Try this code example...

For the js funcion

var csrfName = '<?php echo $this->security->get_csrf_token_name(); ?>',
    csrfHash = '<?php echo $this->security->get_csrf_hash(); ?>';
("#avatar").change(function(){
    var link = $("#avatar").val();

    var dataJson = { [csrfName]: csrfHash, id: "hello", link: link };

    $.ajax({
        url : "<?php echo base_url('main/test'); ?>",
        type: 'post',
        data: dataJson,            
        success : function(data)
        {   
            csrfName = data.csrfName;
            csrfHash = data.csrfHash;
            alert(data.message);
        }  
    });
});

and for the controller

public function test() { 
    $config['upload_path'] = './uploads/'; 
    $config['allowed_types'] = 'gif|jpg|png'; 
    $config['max_size'] = 500; 
    $config['max_width'] = 260; 
    $config['max_height'] = 260; 

    $reponse = array(
                'csrfName' => $this->security->get_csrf_token_name(),
                'csrfHash' => $this->security->get_csrf_hash()
                )

    $this->load->library('upload', $config); 
    if (!$this->upload->do_upload('link')) { 
        $reponse['message'] = "error"; 
    } 
    else { 
        $data = array('upload_data' => $this->upload->data()); 
        $image_name = $data['upload_data']['file_name']; 
        $reponse['message'] = $image_name; 
    } 

    echo json_encode($reponse);
}

Let me know and good luck
