usbxhci: fix wrong control endpoint 0 output device context address

Browse source 
the calculation for the control endpoint0 output device context
missed the context size scaling shift, resulting in botched
stall handling as we would not read the correct endpoint status
value.

note, this calculation only affected control endpoint 0, which
was handled separately from all other endpoints.
