kernel & KernelSU: Deprecated add_try_umount cli, AUTO_ADD_SUS_KSU_DEFAULT_MOUNT and AUTO_ADD_SUS_BIND_MOUNT

Browse Source 
Reason:
 - add_try_umount, AUTO_ADD_SUS_KSU_DEFAULT_MOUNT and AUTO_ADD_SUS_BIND_MOUNT are only used to flag the sus_mount bit on target inode, but actually none of the hooks are checking for this bit, so this is why these features should be no longer needed, and we only need to check for sus mnt_id to determine if it is a sus mount. Plus it takes more CPU cycle to check for the path and set the sus_mount flag during boot time
