qmp command can not be run in the callback of another qmp command.

In file lib/src/qmp.coffee.

The first qmp command set @Datacb and get ready to run @Datacb, the second qmp command in the callback will rewrite @Datacb.
I have do a fix. Please take a look.

Hi @tocaata,

thanks for using this software. I probably have to disappoint you: the coffee version was retired a long time ago.
node-qemu-server faces a complete rewrite in ES6. Now qmp commands just emit the result as an event. Also the UI gets a complete overhaul.
