Remove reference to static mut

Browse Source 
This is what UnsafeCell is for: Providing interior mutability.

The docs at https://doc.rust-lang.org/std/cell/struct.UnsafeCell.html
give an example just like this - `&mut *ptr.get()`

Without, rustc may complain - https://doc.rust-lang.org/nightly/edition-guide/rust-2024/static-mut-references.html
