An error in rbpf

[LiuJun5817]

In this test case, the expected value does not match the output value.

test_interpreter_and_jit_asm!(
        "
        mov32 r0, -1
        add64 r0, 0x1
        exit",
        [],
        (),
        TestContextObject::new(3),
        ProgramResult::Ok(0x0),
    );

interpreter_result is "Ok(0x100000000)", but expected_result is "Ok(0)".
Could the problem be here? "ebpf::MOV32_IMM => self.reg[dst] = insn.imm as u32 as u64,"
