Subject: drm/amdgpu: remove unnecessary save/restore of pdev->d3_delay
Git-commit: ee76380c1e751605fcb0ee1aa3632bcf6fd0bf08
Patch-mainline: v4.13-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Remove unnecessary save/restore of pdev->d3_delay.

The only assignments to pdev->d3_delay are in radeon_switcheroo_set_state()
and some quirks, none of which should be relevant in the
amdgpu_switcheroo_set_state() path.
