[LTP] Issue running cpuset_base_ops_testset shell script

Fri Sep 29 22:44:13 CEST 2017

I applied the patch and investigated a little bit more and resolved
it! Apparently the cpuset route is different!

In centOS, RHEL and Suse cpuset is located in /sys/fs/cgroup/cpuset so
when i unmounted and ran again the tests all of them were successful.

Thanks a lot for your help all of you guys! :)
