Wen Congyang b060d2e5d4 enhance processWatchdogEvent() 
This patch does the following two things:
1. hold an extra reference while handling watchdog event
   If the domain is not persistent, and qemu quits unexpectedly before
   calling processWatchdogEvent(), vm will be freed and the function
   processWatchdogEvent() will be dangerous.

2. unlock qemu driver and vm before returning from processWatchdogEvent()
   When the function processWatchdogEvent() failed, we only free wdEvent,
   but forget to unlock qemu driver and vm, free dumpfile.

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
