zebra: fix fpm crash
Fix issue#11996.
When removing VRF ( all routes of this VRF), zebra mistakenly forgot to check
whether its routes are in update queue of FPM. So FPM module will crash during
its dealing with these routes, which are already freed.
Add a new HOOK `rib_shutdown()`, `zebra_rtable_node_cleanup()` will use it
to remove these routes from update queue of FPM module before freeing them.
