When virNodeDeviceObjListRemove() is called, the passed virNodeDeviceObj is removed from internal list of node devices and then unrefed and unlocked. While the former is warranted (the object was refed at the beginning of the function) the unlock is not. In fact, it's wrong from conceptual POV. We still want threads working on the object tu mutually exclude each other.
