[PATCH v3 3/6] rust: init: add missing newline to pr_info! calls

[Alban Kurti <kurti@xxxxxxxxxx>]

Several pr_info! calls in rust/kernel/init.rs (both in code examples
and macro documentation) were missing a newline, causing logs to
run together. This commit updates these calls to include a trailing
newline, improving readability and consistency with the C side.

Fixes: 6841d45a3030 ("rust: init: add `stack_pin_init!` macro")
Fixes: 7f8977a7fe6d ("rust: init: add `{pin_}chain` functions to `{Pin}Init<T, E>`")
Fixes: d0fdc3961270 ("rust: init: add `PinnedDrop` trait and macros")
Reported-by: Miguel Ojeda <ojeda@xxxxxxxxxx>
Closes: https://github.com/Rust-for-Linux/linux/issues/1139
