commit edaf13565 modified the stats retrieval for OVS interfaces to not fail when one of the fields was unrecognized by the ovs-vsctl command, but ovs-vsctl was still returning an error, and libvirt was cluttering the logs with these inconsequential error messages. This patch modifies the GET_STAT macro to add "--if-exists" to the ovs-vsctl command, which causes it to return an empty string (and exit with success) if the requested statistic isn't in its database, thus eliminating the ugly error messages from the log.
