No, sorry. Netfront looks correct to me.
We take an additional ref for the ref released by
gnttab_release_grant_reference(). The get_page() here is safe since we
haven't freed the page yet (this is done in the subsequent call to
skb_kfree_irq()).
get_page()/put_page() also look fine when used with tail pages.
