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.
