[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 Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S. Miller <davem@davemloft.net>
