Thread-topic:	[PATCH]xend: pass-through: fix "xm pci-list-assignable-devices' for pv_guest

xc.test_assign_device(dev) can only tell us if dev is assigned to hvm guest;
if a device is assigned to pv guest, xc.test_assign_device() still tells us
the device is not assigned yet, as a result, the device still appears in the
output of "xm pci-list-assignable-devices", and xend would not prevent us from
assigning the device to a new pv or hvm guest.

To judge if a device has been assigned to guest, we have to scan xenstore.  

Thanks,
