cgroup: reorganize css init / exit paths
css (cgroup_subsys_state) lifetime management is about to be
restructured. In prepartion, make the following mostly trivial
changes.
* init_cgroup_css() is renamed to init_css() so that it's consistent
with other css handling functions.
* alloc_css_id(), online_css() and offline_css() updated to take @css
instead of cgroups and subsys IDs.
This patch doesn't make any functional changes.
v2: v1 merged two for_each_root_subsys() loops in cgroup_create() but
Li Zefan pointed out that it breaks error path. Dropped.
