ULP usually set IB(V)_QP_AV when trying to modify QP to RTR if they want
to record sgid index into QPC. For UD QPs, it is useless because it will be
included in WQE. For RC QPs, it will be filled in hns_roce_set_path(). So
sgid index shouldn't be filled by default. Then hns_get_gid_index() is
moved to hns_roce_hw_v1.c because it is only called in it.
