[libvirt] [PATCH] libxl: fix AttachDeviceConfig on hostdev type

[Chunyan Liu]

After attach-device a <hostdev> with --config, new device doesn't
show up in dumpxml and in guest.

To fix that, set dev->data.hostdev = NULL after work so that the
pointer is not freed, since vmdef has the pointer and still need it.
