cgroup: add helper for checking when css is cgroup::self
The cgroup struct has a css field called "self". The main difference between this css and the others found in the cgroup::subsys array is that cgroup::self has a NULL subsystem pointer. There are several places where checks are performed to determine whether the css in question is cgroup::self or not. Instead of accessing css->ss directly, introduce a helper function that shows the intent and use where applicable.
