[libvirt] [PATCH] report invalid x86 cpu map error

[zhenwei pi]

Let libvirtd handle invalid x86 cpu map error, and report the real reason.

This issue can be reproduced :
1, rm -rf /share/libvirt/cpu_map
2, start libvirtd
3, virsh create INSTANCE.xml

Libvirtd reports error :
error: invalid argument: Failed to parse group 'tss'

In face, libvirtd gets invalid cpu map.
With this patch, libvirtd reports error :
error: unsupported configuration: invalid x86 cpu map
