usb: gadget: configfs: remove os_desc_attr_release()

it is not allow to create sub group under os_desc,

/sys/kernel/config/usb_gadget/dummy/os_desc # mkdir dummy
mkdir: can't create directory 'dummy': Operation not permitted

no one will kmalloc() os_desc entry and kfree(os_desc) will never be called.
static void os_desc_attr_release(struct config_item *item)
{
       struct os_desc *os_desc = to_os_desc(item);
       kfree(os_desc);
}

remove struct os_desc definition, to_os_desc() and os_desc_attr_release().
