Fix build for io_uring (#9690)

Summary:
Minor fix for build failure:
```
./env/io_posix.h:68:33: error: unused parameter 'len' [-Werror=unused-parameter]
   68 |                          size_t len, size_t iov_len, bool async_read,
      |                          ~~~~~~~^~~
```
Only happens for release build with io_uring.
