codec/rfx: removed unnecessary WaitForSingleObject

Browse Source 
The WaitForSingleObject call on TilePool's event is called with a zero time-out
interval and the event is a manual reset event ... thus no locking or waiting
is involved anyways and Queue_Dequeue may very well return NULL independently
of calling WaitForSingleObject which is already correctly handled.
(cherry picked from commit 938a0890a3)
