RDMA/hns: Compute HEM index in 64-bit in hns_roce_v2_set_hem()

In hns_roce_v2_set_hem() the HEM address indices are computed from
i, j and k (the base-chunk_ba_num decomposition of the 32-bit
table_idx) in 32-bit arithmetic and then assigned to u64 fields.
The recombined value always equals table_idx and cannot exceed
U32_MAX, so this is not a reachable overflow and has no user-visible
impact. Declare i, j and k as u64 so the calculation is done in
64-bit and the pattern no longer trips static analyzers.

No functional change intended.
