net: Rename skb_has_frags to skb_has_frag_list
SKBs can be "fragmented" in two ways, via a page array (called skb_shinfo(skb)->frags[]) and via a list of SKBs (called skb_shinfo(skb)->frag_list). Since skb_has_frags() tests the latter, it's name is confusing since it sounds more like it's testing the former. Signed-off-by: David S. Miller <davem@davemloft.net>
