Subject: [PATCH 5003/5011] cgroup: rename TasksMax structure to CGroupTasksMax

Almost all our enums/structs/funcs carry the CGroup prefix if they are
defined in cgroup.h, TasksMax so far does not, even though it is
exclusively used in cgroup context.

Change that.

(cherry picked from commit 94f0b13b1623c083ece9c0381bd1e65500dc1363)
