Make sure we call fib6_dump_end() if it happens that skb->len
is zero. rtnl_dump_all() can reset cb->args on the next loop
iteration there.

Fixes: 08e814c9e8eb ("net/ipv6: Bail early if user only wants cloned entries")
Fixes: ae677bbb4441 ("net: Don't return invalid table id error when dumping all families")
