Just disable the setup, for example like this:
diff --git a/testcases/kernel/controllers/cpuset/cpuset_funcs.sh
b/testcases/kernel/controllers/cpuset/cpuset_funcs.sh
index a83845c..b178d53 100755

And as I've looked for the the cpuset_funcs.sh I've found that there are two
copies of the file that differ only in one line.
$ find -name cpuset_funcs.sh
./testcases/kernel/controllers/cpuset/cpuset_lib/cpuset_funcs.sh

That is likely.
And after I've rebooted the machine, the tests seems to run fine (the setup is
no longer commented).
I think that the problem is that the cleanup() is not able to cope with the
/dev/cpuset directory left out after killed cpuset01 test. I will look into
this.
