cgroup: refactor mount path and clearly distinguish v1 and v2 paths
While sharing some mechanisms, the mount paths of v1 and v2 are
substantially different. Their implementations were mixed in
cgroup_mount(). This patch splits them out so that they're easier to
follow and organize.
This patch causes one functional change - the WARN_ON(new_sb) gets
lost. This is because the actual mounting gets moved to
cgroup_do_mount() and thus @new_sb is no longer accessible by default
to cgroup1_mount(). While we can add it as an explicit out parameter
to cgroup_do_mount(), this part of code hasn't changed and the warning
hasn't triggered for quite a while. Dropping it should be fine.
