Fixes Hyper-V driver WMI issue on 2008 R2

Trying to assign properties on default Hyper-V resource setting data
WMI objects results in an exceptions before Hyper-V 2012.
Cloning the objects before assigning them solves the issue.

A similar approach was previous already implemented and has been
incorrectly removed during a refactoring.
