Miguel Ojeda a126eca844 rust: avoid unused import warning in rusttest
When compiling for the `rusttest` target, the `core::ptr` import is
unused since its only use happens in the `reserve()` method which is
not compiled in that target:

    warning: unused import: `core::ptr`
    --> rust/kernel/alloc/vec_ext.rs:7:5
      |
    7 | use core::ptr;
      |     ^^^^^^^^^
      |
      = note: `#[warn(unused_imports)]` on by default

Thus clean it.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
