This looks like a different issue. The problem you have identified is
specific to a DHCP agent port being deleted.

Shraddha's question seems to be about all ports. All of the port
information is synced on startup via sync_state here:
https://github.com/openstack/neutron/blob/master/neutron/agent/dhcp/agent.py#L147
so there shouldn't be any issues there.
