[PATCH] rust: rbtree: fix overindented list item

[PATCH] rust: rbtree: fix overindented list item

[Miguel Ojeda]

Starting with Rust 1.86.0 (to be released 2025-04-03), Clippy will have
a new lint, `doc_overindented_list_items` [1], which catches cases of
overindented list items.

The lint has been added by Yutaro Ohno, based on feedback from the kernel
[2] on a patch that fixed a similar case -- commit 0c5928deada1 ("rust:
block: fix formatting in GenDisk doc").

Clippy reports a single case in the kernel, apart from the one already
fixed in the commit above:

    error: doc list item overindented
        --> rust/kernel/rbtree.rs:1152:5
         |
    1152 | ///     null, it is a pointer to the root of the [`RBTree`].
         |     ^^^^ help: try using `  ` (2 spaces)
         |
         = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#doc_overindented_list_items
         = note: `-D clippy::doc-overindented-list-items` implied by `-D warnings`
         = help: to override `-D warnings` add `#[allow(clippy::doc_overindented_list_items)]`

Thus clean it up.

Applied to `rust-fixes` -- thanks everyone!

    [ There are a few other cases, so updated message. - Miguel ]
