[BUG REPORT] 符号查询逻辑不对

[goldwind-ting]

描述错误

DragonOS/kernel/src/debug/traceback/mod.rs

Lines 27 to 31 in ecf7749

	for i in 0..sym_num - 1 {
	if addr > kallsyms_address_list[i] && addr <= kallsyms_address_list[i + 1] {
	index = i;
	break;
	}

如果addr刚好等于kallsyms_adress_list[i+1]，索引index值会是i，但是实际上是i+1

[goldwind-ting]

可以修改为：
let index = match kallsyms_address_list.binary_search(&addr) {
Ok(i) => i,
Err(i) => i - 1,
};
