When linuxNodeInfoCPUPopulate() method triggered use of an
uninitialize value, since it did not initialize the 'sockets'
field in the virNodeInfoPtr struct:
==30020== Conditional jump or move depends on uninitialised value(s)
==30020== at 0x5125DBD: linuxNodeInfoCPUPopulate (nodeinfo.c:513)
==30020== by 0x51261A0: nodeGetInfo (nodeinfo.c:884)
==30020== by 0x149B9B10: qemuCapsInit (qemu_capabilities.c:846)
==30020== by 0x14A11B25: qemuCreateCapabilities (qemu_driver.c:424)
==30020== by 0x14A12426: qemuStartup (qemu_driver.c:874)
==30020== by 0x512A7AF: virStateInitialize (libvirt.c:822)
==30020== by 0x40DE04: daemonRunStateInit (libvirtd.c:877)
==30020== by 0x50ADCE5: virThreadHelper (virthreadpthread.c:161)
==30020== by 0x328CA07D14: start_thread (pthread_create.c:308)
==30020== by 0x328C6F246C: clone (clone.S:114)
(happened twice)
if (socks > nodeinfo->sockets) <--- here
nodeinfo->sockets = socks;
Rather than doing this for each field, just make the caller memset
the entire struct to zero.

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.
