For 2D GPU cores there is a potential need to manage the maximum number
of outstanding return requests from the memory subsystem. The proper way
to manage these for 2D cores with this configuration is to use a FLUSH.
The patch does a FLUSH after every DRAW, the pipe will not overfill and
the scenario which may lead to a stall will not occur.
