Subject: [PATCH v5 04/13] drm/nouveau: Remove useless poll_disable() call in switcheroo_set_state()

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()

[omitting stable Cc, this likely doesn't fix anything important enough
for that]
