Revert "drm/amd: flush any delayed gfxoff on suspend entry"

Browse Source 
commit ab4750332d ("drm/amdgpu/sdma5.2: add begin/end_use ring
callbacks") caused GFXOFF control to be used more heavily and the
codepath that was removed from commit 0dee726395 ("drm/amd: flush any
delayed gfxoff on suspend entry") now can be exercised at suspend again.

Users report that by using GNOME to suspend the lockscreen trigger will
cause SDMA traffic and the system can deadlock.

This reverts commit 0dee726395.
