libxl: fix bug the number of running vcpu inconsistent with config file
The following patch will fix the bug 1825. http://bugzilla.xen.org/bugzilla/show_bug.cgi?id=1825
When using memcpy to update vcpu_online, the high bits of vcpu_online
may unmodified if the size of avail_vcpus less than vcpu_online. So we
need to clear it before the memory copying.
