adjusts the test accordingly.

v3.2.0-22-gc3272e5e1
verify with build:
libvirt-3.2.0-5.virtcov.el7.x86_64
qemu-kvm-rhev-2.9.0-6.el7.x86_64
kernel-3.10.0-663.el7.x86_64
1. create a guest with xml:
<hostdev mode='subsystem' type='mdev' managed='no' model='vfio-pci'>
<source>
<address uuid='9ea4eb07-c4a8-41d1-bd4a-850d1b0bef74'/>
</source>
<address type='pci' domain='0x0000' bus='0x00' slot='0x09' function='0x0'/>
</hostdev>
2. start the guest and check qemu cmd line
#ps -ef |grep kvm
....
-device vfio-pci,id=hostdev0,sysfsdev=/sys/bus/mdev/devices/9ea4eb07-c4a8-41d1-bd4a-850d1b0bef74,bus=pci.0,addr=0x9
....
move to verified.
