[NETFILTER] conntrack_netlink: Fix endian issue with status from userspace
When we send "status" from userspace, we forget to convert the endianness. This patch adds the reqired conversion. Thanks to Pablo Neira for discovering this. Signed-off-by: Harald Welte <laforge@netfilter.org> Signed-off-by: David S. Miller <davem@davemloft.net>
