fix FIONREAD behaviour

Could you try this patch? It should fix the issue.

I found out an interesting behavior about ioctl(FIONREAD). On Linux, calling
ioctl(FIONREAD) to listening socket is failure with EINVAL. This action is
intentional as described in tcp(7). However, it succeeds on native.
This patch makes ioctl(FIONREAD) to listening socket succeeds on Wine.
