[PATCH -next 02/11] cpuset: remove unused assignment to trialcs->partition_root_state

[Chen Ridong]

From: Chen Ridong <chenridong@xxxxxxxxxx>

The trialcs->partition_root_state field is not used during the
configuration of 'cpuset.cpus' or 'cpuset.cpus.exclusive'. Therefore,
the assignment of values to this field can be safely removed.
