It looks duplicated with the one already performed in 'skb_fill_page_desc()'. In fact, it is harmless. 'nr_frags' is written twice with the same value. Once, because of the nr_frags++, and once because of the 'nr_frags = i + 1' in 'skb_fill_page_desc()'. So axe this post-increment to avoid confusion.
