keep_flows was introduced by [1], which used as flag to delete flows or not.
When rehashing or expanding the table instance, we will not flush the flows.
Now don't use it anymore, remove it.

This patch looks good. But its fixing memory leak, I guess the patch
that removed dependedcy on keep_flows is in net-next. so we are good.
