st/nine: Fix aliasing states for stateblocks

If NINE_STATE_FF_MATERIAL is set, the stateblock will upload
its recorded materials matrix.
If NINE_STATE_FF_LIGHTING is set, the lighting set is uploaded.

These flags could be set by a NineDevice9_SetTransform call
or by setting some states related to ff, but that shouldn't trigger
these stateblock behaviours.

We don't need to follow the context states dirtied by render states.
NINE_STATE_FF_VSTRANSF is exactly the state controlling stateblock
updates of transformation matrices, NINE_STATE_FF is too broad.

These two changes avoid setting the two mentionned states when we
shouldn't.
