Currently, if compiler does not support SVE, hns_roce_sve_write512() will be a empty function, which means that this doorbell will be missed when HNS_ROCE_QP_CAP_SVE_DIRECT_WQE is set in qp flag. This patch ensures that driver will at least generate the DB regardless of whether SVE DWQE is supported or not.
