-In f2fs_iget(), we will check inode's first block address, if it is valid,
-we will set FI_FIRST_BLOCK_WRITTEN flag in inode.
-
-But we should only do this for regular inode, otherwise, like special
-inode, i_addr[0] is used for storing device info instead of block address,
-it will fail checking flow obviously.
-
-So for non-regular inode, let's skip verifying address and setting flag.
