[Patch v3] usb: hcd.h: Fix the values of SetHubDepth and GetPortErrorCount to match USB 3.1 specification

[Tal Shorer]

>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.
