[PATCH] Revert "drm/amdgpu/gfx8: Fix compute ring failure after resetting"

[Andrey Grodzovsky]

This reverts commit 75737cb4eb78c7f185e4700b4aa20cf7a3381aca.

Fixes GFX ring test failure after HW reset.
No compute ring test failures were observed with the change reverted.
So seems like whatever problem that change was addressing is not
present anymore.
