FilterDevice: Fix recognition of HUB devices
FilterDevice: Fix recognition of HUB devices

Sometimes UsbDk cannot query device descriptors for USB hubs,
in such cases it does not attach to theirs stack during parent bus
relations processing.

However, since UsbDk is registered as USB hub class filter,
WDF will call its AddDevice callback anyway.

In this case UsbDk should assume that it is dealing with a hub
and assign its usual hub strategy.
