objtool/rust: add one more noreturn Rust function for Rust 1.99.0

commit 5a81c35 upstream.

Starting with Rust 1.99.0 (expected 2026-10-01), under
`CONFIG_RUST_DEBUG_ASSERTIONS=y`, `objtool` may report:

    rust/kernel.o: warning: objtool: _R..._6kernel12module_param9set_paramaEB4_()
    falls through to next function _R..._6kernel12module_param9set_paramhEB4_()

(and many others) due to calls to the `noreturn` symbol [1]:

    core::panicking::panic_null_reference_constructed

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

See commit 56d680d ("objtool/rust: list `noreturn` Rust functions")
for more details.
