cgroup/cpuset: Remove redundant sched domain rebuild from update_prstate()
Both callers of update_prstate(), cpuset_partition_write() and
cpuset_css_killed(), call cpuset_update_sd_hk_unlock() immediately
afterwards. That helper rebuilds sched domains when force_sd_rebuild is
set before releasing the cpuset locks, so the check in update_prstate()
is redundant.
Commit 3bfe47967191 ("cgroup/cpuset: Move
housekeeping_update()/rebuild_sched_domains() together") removed the
same check from cpuset_write_resmask(). Remove the remaining one from
update_prstate().
