Ensure that the cgroup attachment is only applied to a task that has been initialized by WALT. If an uninitialized task is added to the cgroup, it could lead to grp->tasks being corrupted once the task is initialized. Take the situation where cgroup_attach is happening on a task that has not yet woken up, and the task is being attached to top-app cgroup. In the present scenario, such a task would be added to grp->tasks list. Then, when the task is woken up for the first time, WALT initialization would INIT_LIST_HEAD(wts->grp_list), which is normally ok, but for a task that has already inserted in linked list headed by grp->tasks, it ends up corrupting the list.
