drm/amdgpu: Remove unnecessary ras cap check

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
