IoRegisterDeviceInterface() also calls SetupDiCreateDeviceInfo(), so do
we need to make any setupapi calls here at all? I see the flag
DICD_INHERIT_CLASSDRVS differs, but we don't implement that, and I'm not
entirely sure from the documentation what it's supposed to do, or
whether or not it's correct here or in IoRegisterDeviceInterface().
