usb: hub: Send correct wValue to get hub descriptor of a USB 3.0 hub
Testing a USB 3.0 hub by connecting it to the xHCI port on Intel
MinnowMax, when issuing 'get hub descriptor' to the hub, xHCI
reports a transfer event TRB with a completion code 6 which means
'Stall Error'.
In fact super speed USB hub descriptor type is 0x2a, not 0x29.
Sending correct SETUP packet to the hub makes it not stall anymore.
