The current asynchronous command API doesn't return a QMP response when the async command fails. This is easy to reproduce with the balloon command (the sole async command we have so far): run qemu w/o the '-balloon virtio' option and try to issue the balloon command via QMP: no response will be sent to the client. This commit fixes the problem by making qmp_async_cmd_handler() return the handler's error code and then calling monitor_protocol_emitter() if the handler has returned an error.
