drm/nouveau/kms: Fix failure path for creating DP connectors
It looks like that when we moved nouveau over to using drm_dp_aux_init()
and registering it's aux bus during late connector registration, we totally
forgot to fix the failure codepath in nouveau_connector_create() - as it
still seems to assume that drm_dp_aux_init() can fail (it can't).
So, let's fix that and also add a missing check to ensure that we've
properly allocated nv_connector->aux.name while we're at it.
