ht 125cc72c39 gpu: nvgpu: Fix devg_nvgpu_igpu process crash-2. ...

As part of the negative test case we replace the ACR binaries with
corrupted one(by editing the binary in hex editor). The expectaion
is that the process should log the error and exit properly but instead
the process crashed.
The root cause was because NVGPU driver was trying to pause the thread
using nvgpu_nvs_worker_pause but the but NVS isn't initialized at that
point. NVS is initialized after acr init.

Mitigated this failure by adding a checking condition in
nvgpu_nvs_worker_pause.
