In-place DataFrame.reindex
#### Code Sample, a copy-pastable example if possible

```python
df=DataFrame([[1,2],[3,4]], index=list('cd'))
df.reindex(list('dc'), copy=False)

>   0  1
 d  3  4
 c  1  2

df.index

> Index(['c', 'd'], dtype='object')
```
#### Problem description

The index is not re-ordered.

#### Expected Output

> Index(['d', 'c'], dtype='object')

#### Output of ``pd.show_versions()``

[paste the output of ``pd.show_versions()`` here below this line]
