USB: centralize -EREMOTEIO handling
This patch (as969) continues the ongoing changes to the way HCDs
report URB statuses. The programming interface has been simplified by
making usbcore responsible for clearing urb->hcpriv and for setting
-EREMOTEIO status when an URB with the URB_SHORT_NOT_OK flag ends up
as a short transfer.
By moving the work out of the HCDs, this removes a fair amount of
repeated code.
