cgroup: restructure file creation / removal handling
The file creation / removal path has always been a bit icky and the
planned notification update requires css during file creation.
Restructure as follows.
* cgroup_addrm_files() now takes both @css and @cgrp and is only
called directly by other file handling functions.
* cgroup_populate/clear_dir() are replaced with
css_populate/clear_dir() taking @css and @cgrp_override.
@cgrp_override is used only when files needs to be created on /
removed from a cgroup which isn't attached to @css which happens
during subsystem rebinds. Subsystem loops are moved to the callers.
* cgroup_add_file() now takes both @css and @cgrp. @css isn't used
yet but will be used by the planned notification update.
This patch doens't cause any behavior changes.
