This simple change makes id-pool to always allocate the lowest possible id from the pool. No any other code affected because, actually, there is no users of 'id_pool_free_id' in OVS. This behaviour of id-pool will be used in the next patch. Signed-off-by: Ilya Maximets <i.maximets@samsung.com> Signed-off-by: Ben Pfaff <blp@ovn.org>
