arm64: unexport walk_stackframe
The walk_stackframe functions is architecture-specific, with a varying prototype, and common code should not use it directly. None of its current users can be built as modules. With THREAD_INFO_IN_TASK, users will also need to hold a stack reference before calling it. There's no reason for it to be exported, and it's very easy to misuse, so unexport it for now.
