[PATCH] drm/nouveau: Check rc from drm_dp_mst_topology_mgr_resume()

by Lyude Paul

We need to actually make sure we check this on resume since otherwise we won't know whether or not the topology is still there once we've resumed, which will cause us to still think the topology is connected even after it's been removed if the removal happens mid-suspend.
