Subject: drm/nouveau: Remove useless poll_enable() call in drm_load()
Git-commit: 7326ead9828e5eb5c6030d80310241c404e919f9
Patch-mainline: v4.19-rc4
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Again, this doesn't do anything. drm_kms_helper_poll_enable() will have
already been called in nouveau_display_init()
