[NETFILTER] NAT sequence adjustment: Save eight bytes per conntrack
This patch reduces the size of 'struct ip_conntrack' on systems with NAT
by eight bytes. The sequence number delta values can be int16_t, since
we only support one sequence number modification per window anyway, and
one such modification is not going to exceed 32kB ;)
