[PATCH v4 1/2] workqueue: Add missing EXPORT_SYMBOL_GPL for workqueue_set_min_active

["Håkon Bugge" <haakon.bugge@oracle.com>]

Export workqueue_set_min_active() so that tests/loadable modules,
e.g., test-ww_mutex can adjust workqueue concurrency levels to avoid
deadlocks during cyclic test runs. This function is called in
test-ww_mutex.c in order to solve a deadlock.

Fixes: 8f172181f24b ("workqueue: Implement workqueue_set_min_active()")
