Xi: move property reset from extension shutdown to init.

If any part of the stack calls XIGetKnownProperty during device shutdown
the property is re-initialized before the server generation resets, leaving
the value invalid again.

Move the reset to the extension init which happens before input devices are
initialized before the first property is requested.
