[v2] Framework:fix the first numa node may not be '0'
Commit Message
On certain Virtual Machine system such as Power Virtual Machine, PowerVM,
assigns the CPUs of its virtual machines (or Logical Partitions LPARs) to
NUMA nodes, and so the VM (or LPARs) 's CPUs may be on different ID
other than '0'.
This patch should fix that.
v2: correct spelling and remove trailing whitespace
