cpuset: remove impossible warning in update_parent_effective_cpumask

Browse Source 
If the parent is not a valid partition, an error will be returned before
any partition update command is processed. This means the
WARN_ON_ONCE(!is_partition_valid(parent)) can never be triggered, so
it is safe to remove.
