[IPV4] route: use read_mostly
The route table parameters are set based on system memory and sysctl values that almost never change. Also the genid only changes every 10 minutes. RTprint is defined by never used. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
