[PATCH nf-next 1/4] netfilter: ipvs: prepare for hook function reduction

[Florian Westphal <fw@xxxxxxxxx>]

ipvs has multiple one-line wrappers for hooks, compact them.

To avoid a large patch make the two most common helpers use the same
function signature as hooks.

Next patches can then remove the oneline wrappers.
