drm/nouveau/drm/nouveau: Fix runtime PM leak in nv50_disp_atomic_commit()

BugLink: http://bugs.launchpad.net/bugs/1814813
commit e5d54f1935722f83df7619f3978f774c2b802cd8 upstream.

A CRTC being enabled doesn't mean it's on! It doesn't even necessarily
mean it's being used. This fixes runtime PM leaks on the P50 I've got
next to me.
