core: make sure win32 sockets remain blocking

Browse source 
Commit 7e344b5 hade the side effect of forcing every socket to
be non-blocking on Windows. This is because of a (documented)
side effect of WSAEventSelect(). So we need to make sure to restore
blocking behaviour afterwards for relevant sockets.
