[RFC PATCH -v4 07/22] cpuset: use partition_enable() for remote partition enablement

[Ridong Chen]

From: Chen Ridong <chenridong@xxxxxxxxxx>

Now that the partition_enable() helper is available, replace the
existing implementation for remote partition enablement with this
centralized function to unify the enablement logic.
