Virsh shutdown is executed firstly, virsh destroy is executed later,
and VM is recreated again. In this process, due to will delet Domain
object about the new VM in processMonitorEOFEvent(), which
virDomainObjListRemove is called to remove objlist, the new VM
cannot be found through virsh list command and qemu process is still
running. Therefore, add virDomainObjListFindByName function checks
to avoid delet Domain object about the new VM in objlist.

This process chart of problem is as follows

         shutdown           |      destroy     |       create
============================+==================+===================
              qemuMonitorIO |                  |
qemuProcessHandleMonitorEOF |                  |
                            | virDomainDestroy |
                            |  qemuProcessStop |
                            |                  | qemuDomainCreateXML
                            |                  |     qemuProcessInit
     processMonitorEOFEvent |                  |
   qemuDomainRemoveInactive |                  |
                            |                  |   qemuProcessLaunch
