cgroup/cpuset: Use WRITE_ONCE() for shared prs_err updates
cpuset_partition_show() reads cs->prs_err without cpuset_mutex using
READ_ONCE(). The field is documented as not lock protected, but several
updates to live cpusets still use plain stores.
Convert the remaining prs_err stores on live cpusets to WRITE_ONCE().
