qemu: Need to assign PCI address to vhost-scsi

Commit id '70249927b' neglected to cover this case because the test
had taken the "shortcut" to already add the <address>; however, when
the PCI address assignment code was adjusted by commit id '70249927'
the vhost-scsi (VIR_DOMAIN_HOSTDEV_SUBSYS_TYPE_SCSI_HOST) wasn't
covered thus returning a 0 for pciFlags. So I altered the tests too
to make sure it doesn't happen again.

Previously the qemuxml2xmloutdata was a softlink to the source
qemuxml2argvdata, so I unlinked and recreated the output file to
force generation of the adddress. Without the test changes, an
address generation returns:

    libvirt: Domain Config error : internal error: Cannot automatically
    add a new PCI bus for a device with connect flags 00

if an address was supplied in the test, a restart of libvirtd or
edit of a guest would display the following opaque message:

    warning : qemuDomainCollectPCIAddress:1237 :
    qemuDomainDeviceCalculatePCIConnectFlags() thinks that the device
     with PCI address 0000:00:09.0 should not have a PCI address

where the address is related to the guest PCI address provided.
