[PATCH 6.12 479/826] rust: rbtree: fix `SAFETY` comments that should be `# Safety` sections

[Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>]

6.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Miguel Ojeda <ojeda@xxxxxxxxxx>

[ Upstream commit 8333ff4d0799aafbe4275cddcbaf45e545e4efba ]

The tag `SAFETY` is used for safety comments, i.e. `// SAFETY`, while a
`Safety` section is used for safety preconditions in code documentation,
i.e. `/// # Safety`.

Fix the three instances recently added in `rbtree` that Clippy would
have normally caught in a public item, so that we can enable checking
of private items in one of the following commits.
