Subject: [PATCH v5 06/13] drm/nouveau: Call optimus_dsm functions after nouveau_do_suspend()

It's not necessary to call these before we call nouveau_do_suspend().
Ideally; we shouldn't have to call this at all here, but getting that to
work will take a bit more effort. So for the time being, just move this
call after nouveau_do_suspend() to allow us to easily be able to abort
the runtime suspend process in nouveau_do_suspend()
