Description of problem:
When using app-netutil to get podnetinfo for hugepage

# oc exec -n z1 sriov-pod-1 -- ls /etc/podnetinfo
annotations
hugepages_1G_limit_sriov-example
hugepages_1G_request_sriov-example

However the logs show it's using wrong `/etc/podnetinfo/hugepages_request`
see below logs:

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. build one test pod using app-netutil repo
2. setup sriov operator
3. init VF by create policy
4. Create sriovnetwork to create net-attach-def resource
5. Create test pod with image step 1 build

apiVersion: v1
kind: Pod
metadata:
  name: sriov-pod-1
  annotations:
    k8s.v1.cni.cncf.io/networks: mlx277-netdevice
spec:
  containers:
  - name: sriov-example
    image: quay.io/zzhao/app-netutil
    imagePullPolicy: Never
    securityContext:
      privileged: true
    volumeMounts:
    #- mountPath: /etc/podnetinfo
    #  name: podnetinfo
    #  readOnly: false
    - mountPath: /dev/hugepages
      name: hugepage
    resources:
      requests:
        memory: 1Gi
        hugepages-1Gi: 2Gi
        #hugepages-2Mi: 2048Mi
        #cpu: "4"
      limits:
        memory: 1Gi
        hugepages-1Gi: 2Gi

  volumes:
  - name: hugepage
    emptyDir:
      medium: HugePages


6. Check pod logs

7. # oc exec -n z1 sriov-pod-1 -- ls /etc/podnetinfo
annotations
hugepages_1G_limit_sriov-example
hugepages_1G_request_sriov-example
labels



Actual results:

show error:

Expected results:

should use '/etc/podnetinfo/hugepages_1G_limit_sriov-example' to get info other than '/etc/podnetinfo/hugepages_limit'
