[PATCH v2] rust: acpi: replace manual zero-initialization with `pin_init::zeroed()`

[Atharv Dubey <atharvd440@gmail.com>]

Use `pin_init::zeroed()` instead of `core::mem::zeroed()` for initializing
`acpi_device_id`. This removes an explicit unsafe block and aligns ACPI
initialization with the pin-init conversion used across the Rust tree.
