RISC-V: Update the assembler insn testcase.
Since the 0x57 is preserved for the vadd.vv instruction in the integration
branch, remove it to make sure the testcase can work.
gas/
* testsuite/gas/riscv/insn.d: Remove 0x57 since it is preserved
for vadd.vv instruction.
* testsuite/gas/riscv/insn.s: Likewise.
