    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: 2617a91597ca ("* fhandler_socket.cc (get_inet_addr): Handle abstract AF_LOCAL socket.")

    (cherry picked from commit 3b06366ed1b752baa1173fac442702d397485d37)
