Eric Dumazet 2594a2a928 tcp: better use ooo_last_skb in tcp_data_queue_ofo() 
Willem noticed that we could avoid an rbtree lookup if the
the attempt to coalesce incoming skb to the last skb failed
for some reason.

Since most ooo additions are at the tail, this is definitely
worth adding a test and fast path.
