Cannot configure hugepages after bottlerocket 1.27

**Image I'm using:**

Bottlerocket 1.28+ via AWS provided AMI e.g. `bottlerocket-aws-k8s-1.30-x86_64-v1.32.0-cacc4ce9`

**What I expected to happen:**

With the following configuration

```
[settings.boot.kernel-parameters]
"transparent_hugepage" = ["never"]
"hugepages" = ["6550"]
"hugepagesz" = ["2M"]
```

We expect 6550 huge pages are configured

**What actually happened:**

0 huge pages are configured

**How to reproduce the problem:**

Use version 1.28-1.32 of bottlerocket AMI

Reproduce the issue with the Bottlerocket 1.28–1.32 AWS AMI and the settings.boot.kernel-parameters configuration shown in the report. Trace how transparent_hugepage, hugepages, and hugepagesz are handled, and verify that the resulting system reports 6550 configured 2M huge pages rather than zero.
