Miguel Ojeda 21e649b0bd objtool/rust: add one more noreturn Rust function for Rust 1.89.0
commit aa7b65c2a2 upstream.

Starting with Rust 1.89.0 (expected 2025-08-07), under
`CONFIG_RUST_DEBUG_ASSERTIONS=y`, `objtool` may report:

    rust/kernel.o: warning: objtool: _R..._6kernel4pageNtB5_4Page8read_raw()
    falls through to next function _R..._6kernel4pageNtB5_4Page9write_raw()

(and many others) due to calls to the `noreturn` symbol:

    core::panicking::panic_nounwind_fmt

Thus add the mangled one to the list so that `objtool` knows it is
actually `noreturn`.

See commit 56d680dd23 ("objtool/rust: list `noreturn` Rust functions")
for more details.
