Cygwin: fhandler_local: Fix get_inet_addr_local to retrieve correct type

For a datagram socket received by recvfrom, the type param is not
assigned correctly, making fhandler_socket_local::connect() to return
WSAEPROTOTYPE.

Fixes: 2617a91 ("* fhandler_socket.cc (get_inet_addr): Handle abstract AF_LOCAL socket.")
