Debarshi Dutta 9328f057a7 gpu: nvgpu: fix use-after-free use case of CE APP. 
The following issue is reported when running sudo modprobe -r nvgpu

The above issue occurs due to freeing of CIC resources earlier than
dependent users of interrupts e.g. CDE, CE etc.

As a solution, move CIC deinit sequence to end of nvgpu_put.
This handles deinit properly for VGPU/IGPU/DGPU.

Bug 200763510
