    RISC-V: Fix warning in riscv.md
    
    Notice there is warning:
    ../../../riscv-gcc/gcc/config/riscv/riscv.md:1356:32: warning:
    comparison between signed and unsigned integer expressions
    [-Wsign-compare]
           if (INTVAL (operands[2]) == GET_MODE_MASK (HImode))
    ../../../riscv-gcc/gcc/config/riscv/riscv.md:1358:37: warning:
    comparison between signed and unsigned integer expressions
    [-Wsign-compare]
           else if (INTVAL (operands[2]) == GET_MODE_MASK (SImode))
    ../../../riscv-gcc/gcc/config/riscv/riscv.md: In function ‘rtx_def*
    gen_anddi3(rtx, rtx, rtx)’:
    ../../../riscv-gcc/gcc/config/riscv/riscv.md:1356:32: warning:
    comparison between signed and unsigned integer expressions
    [-Wsign-compare]
           if (INTVAL (operands[2]) == GET_MODE_MASK (HImode))
    ../../../riscv-gcc/gcc/config/riscv/riscv.md:1358:37: warning:
    comparison between signed and unsigned integer expressions
    [-Wsign-compare]
           else if (INTVAL (operands[2]) == GET_MODE_MASK (SImode))
    
    Add unsigned conversion to fix this warning.
