From: Bing Bu Cao <mars@xxxxxxxxxxxxxxxxxx>
To retrieve node cpu statistics on Linux system, the
linuxNodeGetCPUstats function simply uses STRPREFIX() to match the
cpuid with the cpuid read from /proc/stat, it will cause
obvious error.
For example:
'virsh nodecpustats 1' will display stats of cpu1* if the latter is online and cpu1 is offline.
This patch fixes this bug.
