SRIOV: fix "Login timeout expired" because of 256 vcpus

The numbers of guest vcpu is better little than the host vcpus' number. But we don't have this host to match 256 cpus. So after discussing we decided to use the same host cpus' number to test guest vcpus. Signed-off-by: Meina Li <[email protected]>
