IB/mlx5: Expose multi-packet RQ capabilities Import Linux upstream commit ccc870879027 ("IB/mlx5: Allow creation of a multi-packet RQ"). Only the create_rq() part was missing: the striding RQ parameters we validate and store on the WQ never reached the firmware. Program two_byte_shift_en, single_stride_log_num_of_bytes and single_wqe_log_num_of_strides, with the two log values encoded relative to their MLX5_MIN_* bases so the 3-bit firmware fields do not truncate them. Upstream renamed these WQ context fields later on, so the names used here are the ones this tree's mlx5_ifc.h still carries.
