Nitin Kumbhar 6789a862e6 gpu: nvgpu: skip nvlink shutdown on invalid gpu state ...

A dGPU can disappear from PCI bus for various reasons. This is
detected while accessing GPU registers and system is rebooted.
If dGPU has disappeared from the system, driver shutdown cannot
access dGPU registers. Skip any such de-initialization (nvlink)
done during shutdown.
