intel/blorp/gen6: Set BLEND_STATEChange only if emitting the blend state

Browse source 
This change is pretty straightforward: if set this field when we don't emit
the blend state, then the garbage at offset=0 will be set as a blend state,
and this will cause artifacts until the proper blend state will be given.
