Description Numan Siddique 2023-05-10 16:11:41 UTC 
Description of problem:

ovn-northd is not syncing the address sets from NB DB to SB DB in some cases.

Regression after the address_set I-P was added.

Steps to reproduce

as_uuid=$(ovn-nbctl --wait=sb create address-set name=as1 addresses=10.16.0.47/4,10.16.3.48/32)

ovn-sbctl list address_set

ovn-nbctl --wait=sb remove address_set $as_uuid addresses 10.16.0.47/4

ovn-sbctl list address_set
