[RFC PATCH -v4 21/22] cpuset: remove prs_err clear when notify_partition_change

[Ridong Chen <ridong.chen@linux.dev>]

From: Chen Ridong <chenridong@huawei.com>

The prs_err should be properly set when partition state is set, it
doesn't have to be reset in notify_partition_change(), just remove it.
