[libvirt] [PATCH 1/1] Fix cpu check for ppc64

 ppc64 pseries architecture requires that the cpus
 be numbered in a certain way.
 According to SMT, if SMT equals 4, 0-3 on core 0,
 4-7 on core 1 and so on. So, depending on how guest
 topology has been specified, one cannot assume that
 the vcpus will be numbered 0-N. For example, for
 smp=2, core=2, threads=1, the two cpus will be 0 and
 4 - one HW thread on each core. libvirt needs to take
 into account.
