[libvirt] [PATCH 14/14] hyperv: Address resource leak found by Coverityo

[Matthias Bolte]

2013/1/9 John Ferlan <jferlan at redhat.com>:
> Because result was used to determine whether or not to free 'priv'
> resources Coverity tagged the code as having a resource leak. This
> change addresses that concern.

The same comment as for the ESX driver in this series applies here.

I'll come up with a patch for this later today.
