RDMA/hns: Bugfix for data type of dip_idx 

dip_idx is associated with qp_num whose data type is u32. However, dip_idx
is incorrectly defined as u8 data in the hns_roce_dip struct, which leads
to data truncation during value assignment.

Fixes: f91696f2 ("RDMA/hns: Support congestion control type selection according to the FW")
