[RISCV] Don't fold RISCVISD::VMV_V_X_VL series node and scalar load to vector load when scalar load is update load

We try to fold RISCVISD::VMV_V_X_VL series node + scalar load -> vector load.
But if scalar load is indexed load (load update form), it's not profitable to fold because load update node can't be removed after fold.
