Input: synaptics_usb - do not rely on input_dev->users

If the device is unused and suspended, a call to open will cause the
device to autoresume through the call to usb_autopm_get_interface().

input_dev->users is already incremented by the input subsystem,
therefore this expression will always be evaluated to true:

	if ((input_dev->users || (synusb->flags & SYNUSB_IO_ALWAYS)) &&
	    usb_submit_urb(synusb->urb, GFP_NOIO) < 0) {
		retval = -EIO;
	}

The same URB will then be fail when resubmitted in synusb_open().

Introduce synusb->is_open to keep track of the state instead.
