RDMA/hns: Bugfix for set hem of SCC
The method of set hem for scc context is different from other contexts. It
should notify the hardware with the detailed idx in bt0 for scc, while for
other contexts, it only need to notify the bt step and the hardware will
calculate the idx.
Here fixes the following error when unloading the hip08 driver:
