AttributeError: 'IntBlock'/'FloatBlock'/etc. object has no attribute 'sp_index'
#### Code Sample, a copy-pastable example if possible

```python
import pandas as pd
# AttributeError: 'IntBlock' object has no attribute 'sp_index'
s = pd.SparseSeries([1, 2])
print(s.where(s >= 2, 0))
# AttributeError: 'FloatBlock' object has no attribute 'sp_index'
df = pd.SparseDataFrame([[1, 2], [3, 4]])
print(df.quantile())
```
#### Problem description

On the surface, SparseSeries and SparseDataFrame should produce the same results as Series and DataFrame, respectively.

#### Expected Output

0    0
1    2
dtype: int64
0    2.0
1    3.0
Name: 0.5, dtype: float64
