MINOR: connection: abort earlier when errors are detected

If an uncaught CO_FL_ERROR flag on a connection is detected, we
immediately go to the wakeup function. This ensures that even if
an error is asynchronously delivered, we don't risk re-enabling
polling or doing unexpected things in the handshake handlers.
