HID: hid-steam: Make client_opened a counter
The client_opened variable was used to track if the hidraw was opened by any clients to silence keyboard/mouse events while opened. However, there was no counting of how many clients were opened, so opening two at the same time and then closing one would fool the driver into thinking it had no remaining opened clients.
