usb: hcd.h: Fix the values of SetHubDepth and GetPortErrorCount to match USB 3.1 specification 

>From the usb 3.1 spec available at http://www.usb.org/developers/docs/
table 10-7 (Hub Class Requests) specifies the values for SetHubDepth and
GetPortErrorCount as:

Request			bmRequestType	bRequest		wValue		wIndex	wLength	Data
SetHubDepth		00100000B	SET_HUB_DEPTH		Hub Depth	Zero	Zero	None
GetPortErrorCount	10100011B	GET_PORT_ERR_COUNT	Zero		Port	Two	Number of Link Errors on this port

Fix these two values to match the spec.
