After a source tree build of the kernel, and having used the `RSCPP`
rule, running `rustfmt` fails with:
error: macros that expand to items must be delimited with braces or followed by a semicolon

When building the rust_print sample with CONFIG_JUMP_LABEL=n, the Rust
static key support falls back to using static_key_count. This function
accepts a mutable pointer to the `struct static_key`, but the Rust
abstractions are incorrectly passing a const pointer.
This means that builds using CONFIG_JUMP_LABEL=n and SAMPLE_RUST_PRINT=y
fail with the following error message:
error[E0308]: mismatched types

| |_____types differ in mutability

= note: expected raw pointer `*mut kernel::bindings::static_key`
found raw pointer `*const kernel::bindings::static_key`

33 | pub fn static_key_count(key: *mut static_key) -> c_int;
| ^^^^^^^^^^^^^^^^
To fix this, insert a pointer cast so that the pointer is mutable.
