Wangyufei (James) 36ae35f02c qemuAgentDispose: Reset lastError 
When an error occurred in qemuAgentIO, it will be saved in mon->lastError,
but it will not be freed at the end.  Present since commit c160ce33;
and compare to commit 9cc8a5af fixing the same problem in qemu_monitor.c.

         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.
