Taku Izumi d5f3320de7 vcpupin: Fix cpu affinity setting bug of qemu driver 
There is the case where cpu affinites for vcpu of qemu doesn't work
correctly. For example, if only one vcpupin setting entry is provided
and its setting is not for vcpu0, it doesn't work.

   # virsh dumpxml VM
   ...
   <vcpu>4</vcpu>
   <cputune>
     <vcpupin vcpu='3' cpuset='9-11'/>
   </cputune>
   ...

   # virsh start VM
   Domain VM started

   # virsh vcpuinfo VM
   VCPU:           0
   CPU:            31
   State:          running
   CPU time:       2.5s
   CPU Affinity:   yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy

   VCPU:           1
   CPU:            12
   State:          running
   CPU time:       0.9s
   CPU Affinity:   yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy

   VCPU:           2
   CPU:            30
   State:          running
   CPU time:       1.5s
   CPU Affinity:   yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy

   VCPU:           3
   CPU:            13
   State:          running
   CPU time:       1.7s
   CPU Affinity:   yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy

This patch fixes this problem.

         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.
