> RAS global isr will only be invoked by hardware interrupt. Don't need to query ras
> capability in isr In addition, amdgpu_ras_interrupt_fatal_error_handler
> ensures the isr won't be called from guest linux side by accident. The RAS cap
> check in isr that introduced to fix sriov crash is not needed any more
