Subject: [PATCH] net: ipv6: change %8s to %s for rt->dst.dev->name in seq_printf
 of rt6_info_route


  the length of rt->dst.dev->name is 16 (IFNAMSIZ)
  in seq_printf, it is not suitable to use %8s for rt->dst.dev->name.
  so change it to %s, since each line has not been solid any more.

  additional information:

    %8s  limit the width, not for the original string output length
         if name length is more than 8, it still can be fully displayed.
         if name length is less than 8, the ' ' will be filled before name.

    %.8s truly limit the original string output length (precision)
