ext4: let ext4_rename handle inline dir
In case we rename a directory, ext4_rename has to read the dir block and change its dotdot's information. The old ext4_rename encapsulated the dir_block read into itself. So this patch adds a new function ext4_get_first_dir_block() which gets the dir buffer information so the ext4_rename can handle it properly. As it will also change the parent inode number, we return the parent_de so that ext4_rename() can handle it more easily. ext4_find_entry is also changed so that the caller(rename) can tell whether the found entry is an inlined one or not and journaling the corresponding buffer head.
