st/mesa: kill instruction if writemask=0 in eliminate_dead_code_advanced()
This fixes a bug where we'd wind up emitting an invalid instruction like
MOVE R[0]., R[1]; - note the empty/zero writemask. If we don't write to
any dest register channels, cull the instruction.
v2: simply change/fix the existing test for instruction culling.
