Yeah, you can also do workqueue_set_max_active(wq, 0) during resume to
restore the default value, which is what's used by alloc_workqueue()

I'll apply the two patches to wq/for-3.14 once David reviews them or
if you wanna take them through the pm tree, that's fine too. I don't
have anything scheduled for wq for the next merge window.
Thanks.
