    Use the server's device list for duplicate detection (#78309)
    
    EvdevAddDevice/EvdevRemoveDevice keep a reference to the device to detect
    duplicate devices based on the dev_t.
    
    EvdevAddDevices was called during PreInit, EvdevRemoveDevice was called during
    DEVICE_CLOSE. That makes it imbalanced if the device succeeds PreInit but the
    server skips everything else because MAX_DEVICES is exceeded. So for all
    devices after MAX_DEVICES, we'd add a reference but never remove it,
    eventually reading/writing past evdev_devices.
    
    The server keeps the list of devices for us anyway, so remove the copy of all
    the pointers and instead run through the device list the server gives us.
