RDMA/hns: Fix wrong fixed value of qp->rq.wqe_shift

The value of qp->rq.wqe_shift of HIP08 is always determined by the number
of sge. So delete the wrong branch.

Fixes: cfc85f3e ("RDMA/hns: Add profile support for hip08 driver")
Fixes: 926a01dc ("RDMA/hns: Add QP operations support for hip08 SoC")
