Waiman Long f9a1767ce3 cgroup/cpuset: Fix incorrect change to effective_xcpus in partition_xcpus_del() 
The effective_xcpus of a cpuset can contain offline CPUs. In
partition_xcpus_del(), the xcpus parameter is incorrectly used as
a temporary cpumask to mask out offline CPUs. As xcpus can be the
effective_xcpus of a cpuset, this can result in unexpected changes
in that cpumask. Fix this problem by not making any changes to the
xcpus parameter.

Fixes: 11e5f407b6 ("cgroup/cpuset: Keep track of CPUs in isolated partitions")
