[libvirt] [PATCH] node_device: more informative error log when device isn't found

[Laine Stump]

In a couple of cases, the node device driver (and the test node device
driver which likely copied it) was only logging "Node device not
found" when it couldn't find the requested device. This patch changes
those cases to log the name (and in the case when it's relevant, the
wwnn and wwpn) as well.
