I believe [`bpo-44806: Fix __init__ in subclasses of protocols`](https://github.com/python/cpython/pull/27545) has caused a regression when using a Dataclass.

In Python `3.9.7`, a `dataclass` that inherits from a subclass of `typing.Protocol` (i.e., a user-defined protocol), does not have the correct `__init__`.

### Demonstration

```python
from dataclasses import dataclass
from typing import Protocol

class P(Protocol):
    pass

@dataclass
class B(P):
    value: str

print(B("test"))
```
In `3.9.7`:
```shell
Traceback (most recent call last):
  File "test.py", line 11, in <module>
    print(B("test"))
TypeError: B() takes no arguments
```
In `3.9.6`:
```shell
B(value='test')
```
