2.6.36-stable review patch.  If anyone has any objections, please let us know.

[ Upstream commit c00b2c9e79466d61979cd21af526cc6d5d0ee04f ]

Somewhere along the lines net_cls_subsys_id became a macro when
cls_cgroup is built as a module.  Not only did it make cls_cgroup
completely useless, it also causes it to crash on module unload.

This patch fixes this by removing that macro.

Thanks to Eric Dumazet for diagnosing this problem.
