Hope this will help you :

Change values from value="<?php echo $datas[0]->customer_id; ?>" to this value="<?=$cust->customer_id;?>"

<select class="form-control" id="customer_id" name="customer_id">
    <?php foreach ( $customer as $cust ){?>
      <option value="<?=$cust->customer_id;?>" <?php if($cust->customer_id == $datas[0]->customer_id) echo 'selected="selected"'; ?> > <?php echo $cust->customer_id; ?></option>
    <?php }?>
</select>
