netfilter: {ip,ip6,nfnetlink}_queue: misc cleanups
- No need to perform data_len = 0 in the switch command, since data_len
is initialized to 0 in the beginning of the ipq_build_packet_message()
method.
- {ip,ip6}_queue: We can reach nlmsg_failure only from one place; skb is
sure to be NULL when getting there; since skb is NULL, there is no need
to check this fact and call kfree_skb().
