[PATCH 2/2] drm/amdgpu: should stop GFX ring in hw_fini

[Liu, Monk]

Sorry, the description of " without disabling gfx ring in hw_fini we would hit GFX hang if a guest VM is destroyed suddenly when running a game" is not correct

Will send another one.

To align with the scheme from gfx9:

without disabling gfx ring in hw_fini we would hit GFX hang if a guest VM is destroyed suddenly when running a game
