The prolugue unwinder rely on symbol info. When PC is not in kernel text address, it cannot find relative symbol info and it will be broken. The guess unwinder will be used in this case. And the guess unwinder code in prolugue unwinder is redundant. Strip it out and set the unwinder type in unwind_state. Make guess_unwinder::unwind_next_frame() as default way when other unwinders cannot unwind in some extreme case.
