    RISC-V: Fix `mode' usage in `riscv_expand_conditional_move'
    
    In `riscv_expand_conditional_move' `mode' is initialized right away from
    `GET_MODE (dest)', so remove needless references that refrain from using
    the local variable.
    
            gcc/
            * config/riscv/riscv.cc (riscv_expand_conditional_move): Use
            `mode' for `GET_MODE (dest)' throughout.
    
    (cherry picked from commit 04c9c27c6f34a1ce1cd4900ccc8dc2521852e8e6)
