[PATCH 6.19 029/844] objtool/rust: add one more `noreturn` Rust function

[ Upstream commit c431b00ca6afc5da3133636ecc34ee7edd38d6cc ]
`objtool` with Rust 1.84.0 reports:
rust/kernel.o: error: objtool: _RNvXNtNtCsaRPFapPOzLs_6kernel3str9parse_intaNtNtB2_7private12FromStrRadix14from_str_radix()
falls through to next function _RNvXNtNtCsaRPFapPOzLs_6kernel3str9parse_intaNtNtB2_7private12FromStrRadix16from_u64_negated()
This is very similar to commit c18f35e49049 ("objtool/rust: add one more
`noreturn` Rust function"), which added `from_ascii_radix_panic` for Rust
1.86.0, except that Rust 1.84.0 ends up needing `from_str_radix_panic`.
Thus add it to the list to fix the warning.
