Avoid an error log when the stop is requested

[WinXaito]

Hi, I do that to serve my FTP server:

go func(srv *ftpserver.FtpServer) {
	<-ctx.Done()
	if err := srv.Stop(); err != nil {
		log.Error().Err(err).Msg("ftpserver: stop error")
	}
}(m.srv)

return m.srv.ListenAndServe()

Note that srv is created like that, with the adapter because I use zerolog:

srv := ftpserver.NewFtpServer(drv)
srv.Logger = adapter.NewWrap(&log.Logger)

Now, when I stop my app, I got this in the log:

27/11/2024 12:25:34.938 ERR Serve error err={"Addr":{"IP":"::","Port":2121,"Zone":""},"Err":{},"Net":"tcp","Op":"accept","Source":null}

I think it's caused by this line. Maybe this method should test if a Stop has been requested and do not throw that error.

I use version 0.24.1.
