Miguel Ojeda 6618d69aa1 rust: print: avoid evaluating arguments in `pr_*` macros in `unsafe` blocks
At the moment it is possible to perform unsafe operations in
the arguments of `pr_*` macros since they are evaluated inside
an `unsafe` block:

    let x = &10u32 as *const u32;
    pr_info!("{}", *x);

In other words, this is a soundness issue.

Fix it so that it requires an explicit `unsafe` block.
