YAMAMOTO Takashi bc0ca51243 netdev_file_ioctl: Fix fcntl F_SETFL O_NONBLOCK regression
This fixes a regression caused by the following commit,
which prevents the file flag from being updated.

```
commit 28860b5242
Author: chao.an <anchao@xiaomi.com>

    net/netdev: fix switch case missing break

    Signed-off-by: chao.an <anchao@xiaomi.com>
```

Note: some applications like mbedtls uses F_GETFL to confirm
the nonblock-ness of the socket. This is critical for such
applications.
