[PATCH rdma-next 2/9] RDMA/hns: Don't overwrite supplied QP attributes
From: Leon Romanovsky <leon@kernel.org>

From: Leon Romanovsky <leonro@nvidia.com>
QP attributes that were supplied by IB/core already have all parameters
set when they are passed to the driver. The drivers are not supposed to
change anything in struct ib_qp_init_attr.
Fixes: 66d86e529dd5 ("RDMA/hns: Add UD support for HIP09")
