NRI pod can't access the device /dev/isst_interface

Hi, all.

Based on my testing about the sst feature in the topology-aware policy. I found that there some problems in the NRI pod.

**The NRI pod can't find the `/host/dev/isst_interface` device.**


After some research, I add these lines to the NRI daemonset.

Then, the NRI pod has no permission to access this device:
```
W0804 01:56:49.287017 1 system.go:297] failed to get SST info for package 0: failed to read SST PP info: Mbox command failed with failed to open isst device "/host/dev/isst_interface": open /host/dev/isst_interface: operation not permitted
```

After that, I noticed that there are some securitycontext in the daemonset file and I modified it:

I added the `privileged: true` into it and I commented the next two lines. At last, the NRI can access the sst device:

So does my approach was correct?

Review the NRI DaemonSet configuration, especially its device mounts and securityContext, then reproduce the SST access failure for /host/dev/isst_interface. Compare the behavior with and without the reported securityContext changes; done when the intended configuration permits the NRI pod to access the device without an unjustified workaround.
