Well, qemuProcessKillManagedPRDaemon() not only kills pr-helper process 
but it also cleans up after it. If we receive DISCONNECTED event then 
qemu is probably unable to talk to pr-helper process even if it is 
running. It makes sense then to kill it and start a new one.
If it is not running then we might clean up after it.
