fuzzing with Tenda_AC15: AttributeError: 'int' object has no attribute 'fileno'

[kirito999]

*Describe the bug
I can not run fuzz_tendaac15_httpd.py in /qiling/examples/fuzzing/tenda_ac15

Sample Code
I use https://github.com/qilingframework/qiling/tree/master/examples/fuzzing/tenda_ac15 and https://kabeor.cn/IoT%E5%9B%BA%E4%BB%B6%E6%8F%90%E5%8F%96%E5%B9%B6%E4%BD%BF%E7%94%A8qiling%E8%BF%9B%E8%A1%8Cfuzz/#IoT-Fuzz

Expected behavior
qiling@ubuntu:~/projects/qiling/examples/fuzzing/tenda_ac15$ python3 fuzz_tendaac15_httpd.py afl_inputs/a

Traceback (most recent call last):
File "/home/qiling/.local/lib/python3.6/site-packages/qiling/os/posix/posix.py", line 281, in load_syscall
ret = syscall_hook(self.ql, *arg_values)

AttributeError: 'int' object has no attribute 'fileno'
Ran once without AFL attached.

sry, I can't solve the issue. Because I am interested in fuzz but I am poor in RE.
