[PATCH 2/2] Revert "drm/amd/amdgpu: fix refcount leak"

[Stefan Bader]

This reverts commit 6c0065eb69de90d50186c04f51ffe889e5bbe037. The 4.19.y
series which this patch comes from has a previous change which is not in
bionic which stores GEM info in the framebuffer. Suspecting that due to
this we actually have no refcount leak in our kernel.
