clutter-event-win32.c: Avoid a Crash

Browse Source 
Commit e70a0109 simplified the dispatching of events by passing the event's
owernership to ClutterStage, but it may be so that any.stage is NULL at
some point on Windows, which will either cause _clutter_stage_queue_event()
to crash or issue a critical warning.  Avoid this problem by checking
whether event->any.stage is not NULL before trying to call
_clutter_stage_queue_event().
