[IPv6]: Fix NULL pointer dereference in ip6_flush_pending_frames
Some of skbs in sk->write_queue do not have skb->dst because
we do not fill skb->dst when we allocate new skb in append_data().
BTW, I think we may not need to (or we should not) increment some stats
when using corking; if 100 sendmsg() (with MSG_MORE) result in 2 packets,
how many should we increment?
If 100, we should set skb->dst for every queued skbs.
If 1 (or 2 (*)), we increment the stats for the first queued skb and
we should just skip incrementing OutDiscards for the rest of queued skbs,
adn we should also impelement this semantics in other places;
e.g., we should increment other stats just once, not 100 times.
*: depends on the place we are discarding the datagram.
I guess should just increment by 1 (or 2).
