[PATCH 3/9] drm/amdgpu/gfx7: Return error code when compute ring tests fail

["Timur Kristóf" <timur.kristof@gmail.com>]

The gfx_v7_0_cp_compute_resume() function should only return
success when all compute rings are actually functional.
This will be especially important for soft reset which needs
this to know whether the reset was successful.
