Currently if ucsi_send_command() fails, then we bail out without
clearing EVENT_PENDING flag. So when the next connector change
event comes, ucsi_connector_change() won't queue the con->work,
because of which none of the new events will be processed.
Fix this by clearing EVENT_PENDING flag if ucsi_send_command()
fails.

I think it would be better to just move that label (out_unlock) above
the point where clear_bit() is already called instead of separately
calling it like that. That way the Connector Change Event will
also get acknowledged.
connector change event
You won't get the next event before the first one was ACK'd, right?
