[PATCH] fsck.f2fs: always fix seg entry type if it is not DATA

[Liu Xue]

If the segment type and sum footer type are node, but its
sit type is corrupted as cold data, this will always trigger
type error crash in do_garbage_collect but not get fixed by fsck,
so fix seg entry type when it is not DATA.
