    Fix `netstat -rs` reporting.

    rttrash (unused but not yet delete entries) were eliminated
     during routing rework. Remove reading these symbols from the kernel.

Hi!
Thank you for submitting the bug report!
I missed that part during the route stack rework.

Does this patch fix an issue for you?

Yes, it does. Thanks.
