  -----------
  [RISCV] Remove pre-assignment of mask vectors during call lowering. NFC (#107192)

The first mask vector operand is supposed to be assigned to V0. No other
vector types will be assigned to V0. We don't need to pre-assign, we can
just try V0 first for any mask vectors in the normal processing.
