[RISCV] Delete unexercised VL=0 vsetvli compatibility logic
The code being removed is technically correct; if we end up with two VL=0 instructions next to each other, we can avoid a state transition if the second is a scalar move. However, since both ops are also nops, we should simply delete them instead. As such, this compatibility rule simply complicates the code for no purpose.
