cgroup/cpuset: Fix error handling in remote_partition_disable()

Browse source

[ Upstream commit 8bf450f3ae ]

When remote_partition_disable() is called to disable a remote partition,
it always sets the partition to an invalid partition state. It should
only do so if an error code (prs_err) has been set. Correct that and
add proper error code in places where remote_partition_disable() is
called due to error.
