cgroup/cpuset: Rename update_unbound_workqueue_cpumask() to update_isolation_cpumasks()

Browse Source 
update_unbound_workqueue_cpumask() updates unbound workqueues settings
when there's a change in isolated CPUs, but it can be used for other
subsystems requiring updated when isolated CPUs change.

Generalise the name to update_isolation_cpumasks() to prepare for other
functions unrelated to workqueues to be called in that spot.

[longman: Change the function name to update_isolation_cpumasks()]
