Miguel Ojeda e8980258c0 objtool/rust: add one more noreturn Rust function for Rust 1.86.0 
commit a3cd5f507b upstream.

Starting with Rust 1.86.0 (see upstream commit b151b513ba2b ("Insert null
checks for pointer dereferences when debug assertions are enabled") [1]),
under some kernel configurations with `CONFIG_RUST_DEBUG_ASSERTIONS=y`,
one may trigger a new `objtool` warning:

    rust/kernel.o: warning: objtool: _R..._6kernel9workqueue6system()
    falls through to next function _R...9workqueue14system_highpri()

due to a call to the `noreturn` symbol:

    core::panicking::panic_null_pointer_dereference

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

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

Cc: stable@vger.kernel.org # Needed in 6.12.y and later (Rust is pinned in older LTSs).
