Let's rework cgroup_config_unload_controller to use the brand new recursive
removal of groups. It saves *lot of* fopen() and fclose() calls:
On my (semi-broken) Fedora 11 with 196 running processes and 3 cgroup
hierarchies, the old cgclear does 668 open("*/tasks"). With the
optimized cgclear, I can see just 22 open("*/tasks") calls.

Jan pointed out that there was a goto missing in the error
handling paths. Fix that bug.

This API will unload the cgroups created in the cgroupfs and
unmount and delete the filesystem mount point. The action is
equivalent to what is done currently in service cgconfig stop.
The reason for this API is to make sure we don't end up with a
asymmetric library API subset. Today an application program can
programatically through cgroup_config_load_config() load a
configuration file, but has no means to cleanup (including all
temporarily created groups).

https://bugzilla.redhat.com/show_bug.cgi?id=502687 mentioned that the directory
was not getting created when a cgconfig start was being run.
This is was because we failed the mkdir. The mkdir for directories at depth
was not succeeding.

I reviewed the libcgroup code in the viewpoint of memory-leak and
found some lacks of fclose(). This patch adds some fclose() calls
for error handling.
