workqueue: Initialize wq_isolated_cpumask in workqueue_init_early()

Now when isolcpus is enabled via the cmdline, wq_isolated_cpumask does
not include these isolated CPUs, even wq_unbound_cpumask has already
excluded them. 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().

Fixes: fe28f631fa94 ("workqueue: Add workqueue_unbound_exclude_cpumask() to exclude CPUs from wq_unbound_cpumask")
