Missing NULL-check in XI2's implementation for get_window()

Browse Source 
Add missing check in gdk_x11_device_manager_xi2_get_window(), returning
NULL if no valid XI2Event* has been found. Calling code seems to be
prepared to handle NULLs coming from this function, so it should be
safe enough (e.g. check gdk_event_source_get_filter_window()).
