[PATCH 6.12.y 46/60] rust: alloc: update module comment of alloc.rs

[Miguel Ojeda <ojeda@kernel.org>]

From: Danilo Krummrich <dakr@kernel.org>

commit 8ae740c3917ff92108df17236b3cf1b9a74bd359 upstream.

Before we remove Rust's alloc crate, rewrite the module comment in
alloc.rs to avoid a rustdoc warning.

Besides that, the module comment in alloc.rs isn't correct anymore,
we're no longer extending Rust's alloc crate.
