update_batch command works with a single where clause . (Just tested)

To archive your goal you have to use foreach with update / replace command

foreach ($data  as $key => $item) {
    $update = array(
        'qty' => $item['qty']
        );

    $this->db->where('no_trans', $item['no_trans']);
    $this->db->where('stock_id', $item['stock_id']);
    $this->db->update('table', $update);

    # or simple way /One Line

    $this->db->update('table', $update, array('no_trans' => $item['no_trans'], 'stock_id' => $item['stock_id'] ));
}
