[AMDGPU] performCvtF32UByteNCombine - revisit node after src operand simplification.

If SimplifyDemandedBits succeeds in simplifying the byte src, add the CVT_F32_UBYTE node back to the worklist as we might be able to simplify further.

Yet another step towards removing SelectionDAG::GetDemandedBits.
