AttributeError in UnixDomainSocketConnection starting v4.1.0

[levincarmel]

Version: v4.1.0

Platform: python 3.9

Description:
I have a ConnectionPool with connection_class=UnixDomainSocketConnection.
In order to verify the socket is unreachable, we send a ping command and expect to get a ConnectionError, but starting v4.1.0 we get an AttributeError instead.

connection_pool = ConnectionPool(
                connection_class=redis.connection.UnixDomainSocketConnection, 
                max_connections = None,
                path=socket_path, 
                "password": password,
                "socket_timeout": socket_timeout,
                "encoding": "utf-8",
                "encoding_errors": "strict",
                "decode_responses": True,
                "retry_on_timeout": False,
)
rc = redis.Redis(connection_pool=connection_pool)

Then I terminate the process that is responsible for the above socket, and do: rc.ping() in order to know the socket is unreachable, from which I expect to get a ConnectionError (this is what we got from the ping in earlier versions).
But instead, in v4.1.0 (and v4.1.1) I get: AttributeError: 'UnixDomainSocketConnection' object has no attribute 'host'.

I investigated a little and seems like changing the socket.error to OSError in connections.py caused ConnectionResetError to get caught by an earlier except clause, where self.host is printed (and of course UnixDomainSocketConnection doesn't have one).
Thanks!
