- iget/iput flow in the dentry recovery process
1. *dir* = f2fs_iget
2. set FI_DELAY_IPUT to *dir*
3. add *dir* to the dirty_dir_list
- __f2fs_add_link
- recover_dentry)
4. iput *dir* by remove_dirty_dir_inode
- sync_dirty_dir_inodes
- write_chekcpoint
If *dir*'s i_count is not 1 (i.e., root dir), remove_dirty_dir_inode is called
later and then iput is triggered again due to the FI_DELAY_IPUT flag.
So, let's unset the flag properly once iput is triggered.
