BUG: read_csv skipfooter fails with invalid quoted line
#### Code Sample, a copy-pastable example if possible

```python
from pandas.compat import StringIO

pd.read_csv(StringIO('''Date,Value
1/1/2012,100.00
1/2/2012,102.00
"a quoted junk row"morejunk'''),  skipfooter=1)

Out[21]
ERROR:root:An unexpected error occurred while tokenizing input
The following traceback may be corrupted or invalid
The error message is: ('EOF in multi-line string', (1, 20))

Error: ',' expected after '"'
```
#### Problem description

This error only happens if the last row has quoting, and is invalid - e.g. delete the `morejunk` above and it does not error.

#### Expected Output

successful parse

pandas 0.19.2
