UnsupportedOperation 'seek' when loading excel files from urllib3.response.HTTPResponse object
0.25.1 seems to have reintroduced #20434 

**Update:** not the case, but the same problem happens when feeding `excel_read()` with an [urllib3.response.HTTPResponse](https://urllib3.readthedocs.io/en/latest/reference/#urllib3.response.HTTPResponse) object. Code sample updated.

#### Code Sample, a copy-pastable example if possible
```
import pandas
import requests

url = "https://raw.github.com/pandas-dev/pandas/master/pandas/tests/io/data/test1.xls"
r = requests.get(url, stream=True)
df = pandas.read_excel(r.raw)
print(df)
```

#### Problem description
Using `0.25.1` I get the same problem and output as described in #20434 with the code above. 

#### Expected Output
See #20434

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