Device allocation issue for multi-container pods with init containers

[haitwang-cloud]

What happened:

Based on PR #1650, device allocation did not properly support multi-container pods that include init containers. This PR attempts to fix device allocation behavior for such cases.

What you expected to happen:

Multi-container pods, including those with init containers, should be able to allocate devices correctly through HAMi, without misassignment or failures.

How to reproduce it (as minimally and precisely as possible):

1. Create a pod spec with multiple containers, including at least one init container that requires device allocation.
2. Deploy to a HAMi-enabled cluster.
3. Observe device allocation results and logs.

Anything else we need to know?:

See #1650 for related fixes and context.

• The output of nvidia-smi -a on your host
• Your docker or containerd configuration file (e.g: /etc/docker/daemon.json)
• The hami-device-plugin container logs
• The hami-scheduler container logs
• The kubelet logs on the node (e.g: sudo journalctl -r -u kubelet)
