Subject: [CLIENT] display proper connected server if multiple servers
 specified

With this change, the dnbd3-client is able to display the selected
server (choosen by the Linux kernel module) after successful probing.
Therefore, the ioctl call OPEN returns the selected server host as
index of the specified dnbd3-server hosts after successful probing.
