Allow usage like `pr_info!("one + 1 = {}", one + 1)` to compile by
ensuring that a reference is taken to the entire expression.
[ The errors we would get otherwise look like:
error[E0277]: `kernel::fmt::Adapter<i32>` doesn't implement `core::fmt::Display`
--> ../samples/rust/rust_minimal.rs:34:9

34 | pr_info!("one + 1 = {}", one + 1);
| ^^^^^^^^^^^^^^^^^^^^--^^^^^^^^^^^

| | required by this formatting parameter
| `kernel::fmt::Adapter<i32>` cannot be formatted with the default formatter
|
= help: the trait `core::fmt::Display` is not implemented for `kernel::fmt::Adapter<i32>`
= note: in format strings you may be able to use `{:?}` (or {:#?} for pretty-print) instead
= help: the trait `core::fmt::Display` is implemented for `kernel::fmt::Adapter<&T>`
= note: this error originates in the macro `$crate::print_macro` which comes from the expansion of the macro `pr_info` (in Nightly builds, run with -Z macro-backtrace for more info)
