Subject: RDMA/hns: Don't overwrite supplied QP attributes
Patch-mainline: v5.15-rc1
Git-commit: e66e49592b690d6abd537cc207b07a3db2f413d0
References: bsc#1190336 stable-5.14.6

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")
