Tim Gardner 4f7760e963 workqueue: Make flush_workqueue() available again to non GPL modules ...

commit 1dadafa86a upstream.

Commit 37b1ef31a5 ("workqueue: move
flush_scheduled_work() to workqueue.h") moved the exported non GPL
flush_scheduled_work() from a function to an inline wrapper.
Unfortunately, it directly calls flush_workqueue() which is a GPL function.
This has the effect of changing the licensing requirement for this function
and makes it unavailable to non GPL modules.

See commit ad7b1f841f ("workqueue: Make
schedule_work() available again to non GPL modules") for precedent.
