cgroup: minor updates around cgroup_clear_directory()
* Rename it to cgroup_clear_dir() and make it take the pointer to the
target cgroup instead of the the dentry. This makes the function
consistent with its counterpart - cgroup_populate_dir().
* Move cgroup_clear_directory() invocation from cgroup_d_remove_dir()
to cgroup_remount() so that the function doesn't have to determine
the cgroup pointer back from the dentry. cgroup_d_remove_dir() now
only deals with vfs, which is slightly cleaner.
This patch doesn't introduce any functional differences.
