[Mesa-dev] [PATCH 2/2] st/clover: Always flush the queue when waiting on an hard_event

The problem is that the queue is only cleared from already signalled events 
when we flush it. And we might not do this if the user only calls 
clWaitForEvents once the corresponding event has already been signalled.

I am fine with not flushing the queue, but we should at least make sure that 
signalled events are freed early enough.
