Michal Privoznik 1cf25f6334 qemuDomainSetNumaParamsLive: Check for NUMA mode more wisely 
https://bugzilla.redhat.com/show_bug.cgi?id=1232663

In one of my previous ptaches (bcd9a564) I've tried to fix the problem
that we blindly assumed strict NUMA mode for guests. This led to
several problems like us pinning a domain onto a nodeset via libnuma
among with CGroups. Once the nodeset was changed by user, well, it did
not result in desired effect. See the original commit for more info.
But, the commit I wrote had a bug: when NUMA parameters are changed on
a running domain we require domain to be strictly pinned onto a
nodeset. Due to a typo a condition was mis-evaluated.

         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.
