nv50/ir: always emit the NDV bit for OP_QUADOP
This silences a divergent error found with F1 2015.
Basically, the NDV bit has to be set when a FSWZ instruction is
inside divergent code, but it's not needed otherwise. The correct
fix should be to set it only in divergent code situations.
GM107 emitter already sets that bit.
