kernel & KernelSU: Replace kabi member susfs_task_state of tast_struct and use tast_struct->thread_info.flags instead; Fix for sus_path not working on some OEM devices; KSU_SUSFS requires CONFIG_THREAD_INFO_IN_TASK now; - Since the kabi member is not guaranteed to be unused by OEM, that is why some deivces may conflict with the kabi member added by susfs, we should use less kabi member as much as possible. - Luckily we have task_struct->thread_info that is enabled by all gki kernels just like kprobes, so we can utilize thread_info->flags for faster check, but it needs CONFIG_THREAD_INFO_IN_TASK to be on which should always be enabled - Big thanks to fatalcoder524 (https://github.com/fatalcoder524) who did an excellent debug process for me Co-authored-by: simonpunk <simonpunk2016@gmail.com>
