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.
