drm/amdgpu: skip disabling fence driver src_irqs when device is unplugged
When performing device unbind or halt, we have disabled all irqs at the
very begining like amdgpu_pci_remove or amdgpu_device_halt. So
amdgpu_irq_put for irqs stored in fence driver should not be called
any more, otherwise, below calltrace will arrive.
