RDMA/hns: Fix wrong fixed value of qp->rq.wqe_shift
[ Upstream commit 0c8b5d6268d92d141bfd64d21c870d295a84dee1 ]
The value of qp->rq.wqe_shift of HIP08 is always determined by the number
of sge. So delete the wrong branch.
Fixes: cfc85f3e4b7f ("RDMA/hns: Add profile support for hip08 driver")
Fixes: 926a01dc000d ("RDMA/hns: Add QP operations support for hip08 SoC")
