IPVS: Move IPVS to net/netfilter/ipvs

Since IPVS now has partial IPv6 support, this patch moves IPVS from
net/ipv4/ipvs to net/netfilter/ipvs. It's a result of:

$ git mv net/ipv4/ipvs net/netfilter

and adapting the relevant Kconfigs/Makefiles to the new path.

- * Changes:
- *     Wensong Zhang            :     changed the ip_vs_wlc_schedule to return dest
- *     Wensong Zhang            :     changed to use the inactconns in scheduling
- *     Wensong Zhang            :     changed some comestics things for debugging
- *     Wensong Zhang            :     changed for the d-linked destination list
- *     Wensong Zhang            :     added the ip_vs_wlc_update_svc
- *     Wensong Zhang            :     added any dest with weight=0 is quiesced
