cls_cgroup: Fix crash on module unload 

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.
