[libvirt RFC PATCH 5/5] conf: replace virDomainDeviceInfoClear with virDomainDeviceInfoFreeContents

[Laine Stump]

In every case where virDomainDeviceInfoClear() is still being called,
the object containing the DeviceInfo is freed immediately thereafter
(yes, I checked them all!). This means we don't need to clear any of
the data in the DeviceInfo, just free memory that it points to.
