[PATCH v2 2/2] drm/nouveau: Don't pm_runtime_put_sync(), only pm_runtime_put_autosuspend()

[Lyude Paul]

While trying to fix another issue, it occurred to me that I don't actually
think there is any situation where we want pm_runtime_put() in nouveau to
be synchronous. In fact, this kind of just seems like it would cause
issues where we may unexpectedly block a thread we don't expect to be
blocked.

So, let's only use pm_runtime_put_autosuspend().

Changes since v1:
* Use pm_runtime_put_autosuspend(), not pm_runtime_put()
