Growtopia shows a popup when this function call fails, faking success gets rid of it. Unreal Editor also prints a warning message that is silenced through this change.

Previously, `SetupDiGetINFClassW()` read INF files
with `GetPrivateProfileString()`, which does not substitute %strkey%
tokens.
This caused device installation to fail for devices which had driver
INF files using %strkey% tokens in Version section.
An example of such device is Vernier LabQuest Mini (08f7:0008) for
which Vernier's LoggerPro application includes a driver.
The INF file in question adds a new device setup class and has
following entries in Version section:
```
Class = %ClassName%
ClassGuid = %DeviceClassGUID%
```
Strings section includes following entries:
```
DeviceClassGUID = "{6B8429BF-10AD-4b66-9FBA-2FE72B891721}"
ClassName = "VST_WinUSB"
```
Previously, when LoggerPro was installed and LabQuest Mini was
hotplugged, device installation failed with the following error:
```
fixme:setupapi:SetupDiGetINFClassW failed to convert "L"%DeviceClassGUID"" into a guid
```
This caused GUID_NULL to be used and Class was not set to the registry
for the device.
With this commit, correct class GUID and names are set to the device
registry entry.
