It seems we need to use the inode block passing by fsck_failed_reconnect_file().

3012                         fsck->chk.valid_blk_cnt--;
3013                         if (addr == NEW_ADDR)

And, we also need to skip if addr == COMPRESS_ADDR here?

3014                                 continue;
3015                         f2fs_clear_main_bitmap(sbi, addr);
3016                 }
