Fix cpuid KVM crash on i386 (Lubomir Rintel)
Cpuid should return into vec, not overwrite past address in count. Changeset 6565 broke this. Signed-off-by: Lubomir Rintel <lkundrak@v3.sk> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6689 c046a42c-6fe2-441c-8c8c-71466251a162
