f2fs: handle unallocated section and zone on pinned/atgc
If we have large section/zone, unallocated segment makes them corrupted. E.g., - Pinned file: -1 119304647 119304647 - ATGC data: -1 119304647 119304647 Reviewed-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
