USB: Add stream ID field to struct urb.
Bulk endpoint streams were added in the USB 3.0 specification. Streams
allow a device driver to overload a bulk endpoint so that multiple
transfers can be queued at once.
Add a new field, stream_id, to struct urb so that USB 3.0 drivers can
specify which stream they want the URB to be queued to.
