Alex Jia ecf75f83dc virsh: plug memory leak on cmdBlkdeviotune() sucessful path 
Detected by valgrind. Leak introduced in commit e9bd9a0:

* tools/virsh.c: fix memory leak on cmdBlkdeviotune.

* how to reproduce?
  % valgrind -v --leak-check=full virsh blkdeviotune <domain name> <block device>

* actual valgrind result:

         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.
