gpu-compute: No RF scheduling in case of SKIP or EMPTY

In case of flat memory instructions the status for the
LM pipe execution unit is set to SKIP or EMPTY, as the bus
between the VRF and the GM and LM pipe is shared. The
destination operands should not be scheduled for the LM pipe,
event if the wave is in the dispatch list. This can lead
to deadlock in the destination cache as DCEs are reused
and the slotsAvailableForBank count gets artificially
incremented.
