RISC-V: Remove the redundant expressions in the and<mode>3.

When generating the gen_and<mode>3 function based on the and<mode>3
template, it produces the expression emit_insn (gen_rtx_SET (operand0,
gen_rtx_AND (<mode>, operand1, operand2)));, which is identical to the
portion I removed in this patch. Therefore, the redundant portion can be
deleted.
