qemu: Close the agent connection only on agent channel events
processSerialChangedEvent processes events for all channels. Commit
2af51483 broke all agent interaction if a channel other than the agent
closes since it did not check that the event actually originated from
the guest agent channel.

And in step6, "virsh shutdown rhel7.0" lead the guest to suspended state. Libvirtd.log attached. Expected results: After log into the guest, guest agent should work well as normal. And guest should not enter suspended state in step6. Additional info: A guest without graphical user interface doesn't have such problem.
