conf: fix crash when parsing a unordered NUMA <cell/>
https://bugzilla.redhat.com/show_bug.cgi?id=1260846 Introduced by 8fedbbdb, if we parse an unordered NUMA cell, will get a segfault. This is because of a check for overlapping @cpus sets we have there. However, since the array to hold guest NUMA cells is allocated upfront and therefore it contains all zeros, an out of order cell will break our assumption that cell IDs have increasing character. At this point we try to access yet NULL bitmap and therefore segfault. Signed-off-by: Luyao Huang <lhuang@redhat.com>

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. Daniel Veillard <veillard@redhat.com>
Description
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
