[IPV4] ROUTE: Collect proc-related functions together
The net/ipv4/route.c file declares some entries for proc to dump some routing info. The reading functions are scattered over this file - collect them together. Besides, remove a useless IP_RT_ACCT_CPU macro. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
