[PATCH] rust: fix off-by-one line number in rustdoc tests

[Gary Guo]

From: Gary Guo <ga...@garyguo.net>

When the `#![allow]` line was added, the doctest line number anchor
isn't updated which causes the line number printed in kunit test to be
off-by-one.

Fixes: ab844cf32058 ("rust: allow `unreachable_pub` for doctests")
