Alex Jia b41d440e61 qemu: Avoid memory leaks on qemuParseRBDString 
Detected by valgrind. Leak introduced in commit 5745dc1.

* src/qemu/qemu_command.c: fix memory leak on failure and successful path.

* How to reproduce?
% valgrind -v --leak-check=full ./qemuargv2xmltest

* Actual 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.
