The idea of the warning in ext4_update_dx_flag() is that we should warn when we are clearing EXT4_INODE_INDEX on a filesystem with metadata checksums enabled since after clearing the flag, checksums for internal htree nodes will become invalid. So there's no need to warn (or actually do anything) when EXT4_INODE_INDEX is not set.
