[Nouveau] drm/nouveau: lockdep circular locking dependency report

[Mike Galbraith]

I've now applied a revert of 551620f2a3816397266dfd812cd8b3be89f14be4
to all trees where lockdep may be enabled to re-hide the inversion.  It
thus won't every remind me of its existence, thus I won't be inspired
to pass that reminder along.
