It is only when we successfully configure an isolate cpuset partition that wq_isolated_cpumask gets overwritten by workqueue_unbound_exclude_cpumask(), including both the cmdline-specified isolated CPUs and the isolated CPUs within the cpuset partitions. Fix this issue by initializing wq_isolated_cpumask properly in workqueue_init_early().
