Subject: drm/nouveau: Remove useless poll_disable() call in
 switcheroo_set_state()
Git-commit: 0d7b2d4def679cae3bf2728fc31be7f8a48ceab3
Patch-mainline: v4.19-rc4
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

This won't do anything but potentially make us miss hotplugs. We already
call drm_kms_helper_poll_disable() in
nouveau_pmops_suspend()->nouveau_display_suspend()->nouveau_display_fini()
