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.
