      Steps to reproduce:

      • Create a logical router, add a logical router port to it and create a static mac binding referencing that port by name
      • Delete the logical router

      ovn-northd continuously fails to commit to the SB database because it would violate referential integrity.

      E.g., in a sandbox:

      > ovn-nbctl lr-add lr -- lrp-add lr lrp 00:00:00:00:00:01 1.1.1.1/24
> ovn-nbctl static-mac-binding-add lrp 1.1.1.2 00:00:00:00:00:02
> ovn-nbctl lr-del lr

> ovn-nbctl -t 5 --wait=sb sync
2024-07-29T14:09:00Z|00001|fatal_signal|WARN|terminating with signal 14 (Alarm clock)
Job 1, 'ovn-nbctl -t 5 --wait=sb sync' terminated by signal SIGALRM (Timer expired)

      Northd logs show the referential integrity violation:

      2024-07-29T14:09:25.064Z|00017|ovsdb_idl|WARN|transaction error: {"details":"cannot delete Datapath_Binding row ba0b001b-7272-4886-ac83-913079c0b171 because of 1 remaining reference(s)","error":"referential integrity violation"}
