win32u: Downgrade the NtOpenFile ERR to a WARN in add_device().

This may fail for multiple legitimate reasons. Most commonly, the device may not actually be present on the machine (it will appear in the registry regardless). Less commonly, the device may have been removed between the call to NtEnumerateKey and here. We can get around the former by checking the Linked subkey value, but there is not much point; failing to open the file gives us just as much information.
