roll back the parameter check of AsyncInterruptTransfer() and SyncInterruptTransfer() of Usb2HcProtocol to follow current uefi spec.
current uefi spec only supports interrupt in endpoint.
but there are usb devices which support interrupt out endpoint. we propose to update uefi spec to remove the limitation. after the ecr is approved, the corresponding patch will be submitted.
