ext4: Don't set EXTENTS_FL flag for fast symlinks
For fast symbolic links, the file content is stored in the i_block[] array, which is not compatible with the new file extents format. e2fsck reports error on such files because EXTENTS_FL is set. Don't set the EXTENTS_FL flag when creating fast symlinks. In the case of file migration, skip fast symbolic links.
