Subject: [PATCH v3 4/6] rust: sync: add missing newline in locked_by log
 example

The pr_info! example in rust/kernel/sync/locked_by.rs was missing
a newline. This patch appends the missing newline to ensure
that log messages for locked resources display correctly.

Fixes: 7b1f55e3a984 ("rust: sync: introduce `LockedBy`")
Reported-by: Miguel Ojeda <ojeda@...nel.org>
Closes: https://github.com/Rust-for-Linux/linux/issues/1139
Signed-off-by: Alban Kurti <kurti@...icto.ai>
