[XFRM/RTNETLINK]: Decrement qlen properly in {xfrm_,rt}netlink_rcv().
If we free up a partially processed packet because it's skb->len dropped to zero, we need to decrement qlen because we are dropping out of the top-level loop so it will do the decrement for us. Spotted by Herbert Xu. Signed-off-by: David S. Miller <davem@davemloft.net>
