Subject: [PATCH 2/4] NET : makes ipv4 use the  {DEFINE|REF}_PROTO_INUSE infrastructure

Trivial patch to make "tcp,udp,udplite,raw" protocols uses the fast 
"inuse sockets" infrastructure

Each protocol use then a static percpu var, instead of a dynamic one. 
This saves some ram and some cpu cycles
