[PATCH v16 1/4] rust: remove redundant `as _` casts

[Tamir Duberstein <tamird@gmail.com>]

Remove redundant casts added in commit 1bd8b6b2c5d3 ("rust: pci: add
basic PCI device / driver abstractions") and commit 683a63befc73 ("rust:
platform: add basic platform device / driver abstractions")

While I'm churning this line, move the `.into_foreign()` call to its own
statement to avoid churn in the next commit which adds a `.cast()` call.

Fixes: 1bd8b6b2c5d3 ("rust: pci: add basic PCI device / driver abstractions")
Fixes: 683a63befc73 ("rust: platform: add basic platform device / driver abstractions")
