[PATCH v3 6/6] rust: samples: add missing newline to pr_info! calls in rust_print_main

[Alban Kurti]

The sample code in samples/rust/rust_print_main.rs contained pr_info!
calls without a newline. This commit updates those calls, ensuring
that the output is properly formatted when the sample is run.

Fixes: f431c5c581fa ("samples: rust: print: Add sample code for Arc printing")
Fixes: 47cb6bf7860c ("rust: use derive(CoercePointee) on rustc >= 1.84.0")
Reported-by: Miguel Ojeda <ojeda@xxxxxxxxxx>
Closes: https://github.com/Rust-for-Linux/linux/issues/1139
