[libvirt] [PATCH 1/3] qemu: Wait for monitor socket even without pid
If qemuMonitorOpenUnix is called without a related pid, i.e. for
QMP probing, a connect failure can happen as the result of a race.
Without a pid there is no retry and thus we give up to early.
This changes the code to retry if no pid is supplied.
