When created new guest on NUMA server, xend tried to get the best node
by calculated all vcpus info, if domain already be terminated then
getVCPUInfo() will throw below exception and guest start failed:
[2013-09-04 20:01:26 6254] ERROR (XendDomainInfo:496) VM start failed
Traceback (most recent call last):

raise XendError(str(exn))
XendError: (3, 'No such process')
This patch will check return value of xc.vcpu_getinfo() and make sure the
error not caused by domain died before throw the exception.
