drm/amdgpu: omitir switch_power_profile de gfx durante el restablecimiento de la GPU

Durante la reanudación tras un restablecimiento de la GPU, el trabajo de inactividad de gfx puede invocar switch_power_profile antes de que el restablecimiento se complete. Esto provoca el siguiente error de aserción, porque el acceso a registros se produce sin liberar primero el semáforo de restablecimiento de la GPU:
