4.20-stable review patch. If anyone has any objections, please let me know.

commit c35828ea906a7c76632a0211e59c392903cd4615 upstream.
Immediate packets sent to hardware should include the work request length in calculating the flits. WR occupy one flit and if not accounted result in invalid request which stalls the HW queue.
