objtool/rust: add one more `noreturn` Rust function for Rust 1.86.0
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 56d680dd23c3 ("objtool/rust: list `noreturn` Rust functions")
for more details.
Cc: [email protected] # Needed in 6.12.y and later (Rust is pinned in older LTSs).
