Calling write on a ServerSocketChannel fatal errors with bogus message

[weissi]

Expected behavior

Calling write on a ServerSocketChannel should fail the promise with ChannelError.unsupportedOperation.

Actual behavior

It fatal errors with a bogus message that suggests the subclass (which is ServerSocketChannel must implement a method)

Steps to reproduce

1. create a server bootstrap
2. bind
3. .wait/.then
4. write to the Channel returned (which is a ServerSocketChannel)

If possible, minimal yet complete reproducer code (or URL to code)

    let bootstrap = ServerBootstrap(group: group)
       .childChannelOption(ChannelOptions.socket(SocketOptionLevel(SOL_SOCKET), SO_REUSEADDR), value: 1)
    defer {
        try! group.syncShutdownGracefully()
    }
    try! bootstrap.bind(host: "127.0.0.1", port: 12345).wait().write(NIOAny("foo bar")).wait()

then connect to port 12345
