cgroup: Remove unused cgroup_subsys::post_attach

Browse source

cgroup_subsys::post_attach callback was introduced in commit 5cf1cacb49
("cgroup, cpuset: replace cpuset_post_attach_flush() with
cgroup_subsys->post_attach callback") and only cpuset would use this
callback to wait for the mm migration to complete at the end of
__cgroup_procs_write(). Since the previous patch defer the flush operation
until returning to userspace, no one use this callback now. Remove this
callback from cgroup_subsys.
