Optimize memcg_get_hierarchical_limit to save cpu cycle.

I can't understand the benefit of this patch to the real world...

So, if you wrote the patch description as "clean up" rather than optimize,
ok, I'll agree.

OK, I will change to "Cleanup". Thank you Kame.

Does this really clean something up?

I just thought unused variable is trash even if it disappears after complie.

Thanks,
