When I checked all the place where calling qemuDriverLock(), I found
some problem. The details of the problem is here:
https://www.redhat.com/archives/libvir-list/2011-March/msg01409.html
When I modify the function processWatchdogEvent(), I found that
wdEvent->vm may be freed before processWatchdogEvent() is called.

qemu: avoid qemu_driver being unlocked twice when virThreadPoolNew()
failed
qemu: unlock qemu driver and vm before returning from
processWatchdogEvent()
hold an extra reference while handling watchdog event
