fanyang e3f089251c fix(ospf): mitigate route sync storm under connection flapping (#2063)
Addresses issue #2016 where nodes behind unstable networks
(e.g. campus firewalls) cause excessive traffic that can freeze
the remote node.

Two changes in peer_ospf_route.rs:

- Make do_sync_route_info only trigger reverse sync_now when
  incoming data actually changed the route table or foreign
  network state.  The previous unconditional sync_now created
  an A->B->A->B ping-pong cycle on every RPC exchange.

- Add exponential backoff (50ms..5s) to session_task retry loop.
  The previous fixed 50ms retry produced ~20 RPCs/s during
  sustained network instability.
