When subnet or gateway port has been deleted concurrently, rpc call to get_subnet_for_dvr will return an empty dict without any value. ovs_dvr_neutron_agent should be more gracefull and at least log warning message in that situation. Change the existing error log to warning, because it is not a server error, but a fact that should be noticed. Change-Id: Icb3a57553a8b0eb635c0d85e2c60e7ce519893f6 Closes-bug: #1454921
