[PATCH] cgroup.c: Some 'hlist_head' function fixes.

[Rakib Mullick]

Hello guys, the following patch emphasizes on two things:
	1. We can carry out the following function with one variable.
	2. As hash_long returns with unsigned long we need a unsigned long to
handle this.
If anything else, please notice.
Thanks.
