From: Yangyang Li <liyangyang20@huawei.com>

When query_qp is called by userspace, max_send_wr and max_send_sge are set
to 0 by the kernel driver. However, the userspace does not use these two
return values from the kernel driver, but uses its own calculated values.
So there is no need for special treatment.

Fixes: 926a01dc000d ("RDMA/hns: Add QP operations support for hip08 SoC")
