If the function lxcSetupLoopDevices(def, &nloopDevs, &loopDevs) failed, the variable loopDevs will keep a initial NULL value, however, the function VIR_FORCE_CLOSE(loopDevs[i]) will directly deref it. This patch also fixes returning a bogous number of devices from lxcSetupLoopDevices on an error path. * rc/lxc/lxc_controller.c: fixed a null pointer dereference.

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.
