From: Yixian Liu <liuyixian@huawei.com>

As the qp access right is checked and setted in common function
hns_roce_v2_set_opt_fields(), there is no need to set again for a special
case INIT2INIT.

Fixes: 926a01dc000d ("RDMA/hns: Add QP operations support for hip08 SoC")
Fixes: 7db82697b8bf ("RDMA/hns: Add support for extended atomic in userspace")
