Patch Review

**Correctness: OK**

The transformation is sound. Before the patch:

```rust
Ok(BiosImageType::PciAt) =3D> {
    if pci_at_image.is_none() {
        pci_at_image =3D Some(PciAtBiosImage::try_from(image)?);
    }
}
```

When `pci_at_image.is_some()`, the arm body runs but skips the assignment =
=E2=80=94 effectively a no-op.

After the patch:

```rust
Ok(BiosImageType::PciAt) if pci_at_image.is_none() =3D> {
    pci_at_image =3D Some(PciAtBiosImage::try_from(image)?);
}
```

When `pci_at_image.is_some()`, the match guard fails, Rust continues patter=
n matching, `Ok(BiosImageType::FwSec)` doesn't match (the code_type is PciA=
t), and execution falls through to `_ =3D>` which is a no-op. Behavior is i=
dentical.

**Minor nit =E2=80=94 comment placement:**

```rust
Ok(BiosImageType::PciAt) if pci_at_image.is_none() =3D> {
    // Silently ignore any extra PCI-AT images.
    pci_at_image =3D Some(PciAtBiosImage::try_from(image)?);
}
```

The comment "Silently ignore any extra PCI-AT images" now sits inside the a=
rm that only fires for the *first* PCI-AT image (where we actually *process=
* it, not ignore it). The ignoring now happens implicitly via fall-through =
to `_ =3D>`. The comment still makes sense as explaining *why* the guard ex=
ists, but it could be slightly misleading to a reader who interprets it as =
describing what this arm body does. Consider moving it above the match arm:

```rust
// Silently ignore any extra PCI-AT images.
Ok(BiosImageType::PciAt) if pci_at_image.is_none() =3D> {
    pci_at_image =3D Some(PciAtBiosImage::try_from(image)?);
}
```

This is a very minor style nit and not worth blocking the patch over.

**No other issues.** The patch does what it says =E2=80=94 no functional ch=
ange, just collapsing the `if` into a match guard to satisfy clippy.
