netfilter: ctnetlink: remove incorrect spin_[un]lock_bh on NAT module autoload
Since 7d367e0, ctnetlink_new_conntrack is called without holding the nf_conntrack_lock spinlock. Thus, ctnetlink_parse_nat_setup does not require to release that spinlock anymore in the NAT module autoload case. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: David S. Miller <davem@davemloft.net>
