Allow driver to call DeleteInputDeviceRequest during UnInit
When the input driver (like xf86-input-wacom) removes it's devices
during a call to UnInit, the CloseDownDevices() cannot handle it. The
"next" variable can become a pointer to freed memory.
The patch introduces order-independent device freeing mechanism by
remembering the already freed device ids. The devices can reorder any
time during freeing. No device will be double-freed - if the removing
failed for any reason; some implementations of DeleteInputDeviceRequest
don't free the devices already.
