When constructing QMP capabilities we allocate a dummy domain object to pass to qemuMonitorOpen(). However, after 75dd595861 the function also expects domain definition to be allocated for the domain object. The referenced commit already fixed qemumonitortestutils.c but forgot to fix the other caller: qemuProcessQMPConnectMonitor().
