[PATCH] ipvs: change type of delta and previous_delta in ip_vs_seq.

In NAT forwarding mode, Applications may decrease the size of packets,
and TCP sequences will get smaller, so both of variables will be negetive
values in this case.

	As long as nobody cares about their sign, the type should not
matter. You can not solve all signed/unsigned mismatches with such
small patch. Or you are seeing some problem, may be in debug?
