[Suggestion] net-ipv6: format %8s change to %16s in rt6_info_route function of route.c

[Chen Gang <gang.chen@asianux.com>]

Hello:

1) For Public Kernel:

   A) in rt6_info_route function of net/ipv6/route.c

   B) the length of rt->rt6i_dev->name is 16 (IFNAMSIZ)

   C) using %16s is better than %8s (it will be more "beautiful")
      (also suggest to delete RT6_INFO_LEN, it is useless for ever)



2) For Red Hat RHEL5:

   A) in rt6_info_route function of net/ipv6/route.c

   B) the length of rt->rt6i_dev->name is 16 (IFNAMSIZ)

   C) for RT6_INFO_LEN is still useful, so it is an correctness issue.

   the relative patch for RHEL5 is below:
