Weird.  Are you sure that patch was correctly applied?

On my machine:

[ovs]# wget -c 
https://patchwork.ozlabs.org/project/openvswitch/patch/[email protected]/mbox/
 --content-disposition
[ovs]# git am -3 ovs-dev-ovsdb-idl-Add-memory-report-function..patch
[ovs]# make -j8 sandbox
[tutorial]# ovs-appctl memory/show
idl-cells:17
[tutorial]# ovs-vsctl add-br br-int
[tutorial]# ovs-appctl memory/show
handlers:11 idl-cells:96 ports:1 revalidators:5 rules:5
[tutorial]# ovs-vsctl del-br br-int
[tutorial]# ovs-appctl memory/show
idl-cells:17

Best regards, Ilya Maximets.
