[03/28] ext4: ext4_mkdir should dirty dir_block with the parent inode

ext4_mkdir calls ext4_handle_dirty_metadata with dir_block and the inode "dir".
Unfortunately, dir_block belongs to the newly created directory (which is
"inode"), not the parent directory (which is "dir").  Fix the incorrect
association.

could you please re-send this patch and other fixes that isn't related
to metadata checksum? I need this when implementing inlined dir, and I
guess this can be merged in this merge window.

Thanks

Just FYI it's patches 1-5 of this patchset, but I'm happy to resend.
