Subject: kABI: protect struct rtable
Patch-mainline: never, kabi
References: kabi

In networking-stable-18_11_21, upstream commit
d52e5a7e7ca49457dd31fc8b42fb7c0d58a31221 (ipv4: lock mtu in fnhe when
received PMTU < net.ipv4.route.min_pmtu) changed rt_pmtu u32 in struct
rtable to two bitmasks of the same size. It made the kABI checker to
complain.

Given the size of the structure did not change and rt_pmtu is used only
internally, hide the change from the kABI checker.
