RDMA/hns: Remove unused variables and definitions

Some code was removed but the variables were still there, and some
parameters have been changed to be queried from firmware. So the
definitions of them are no longer needed.

Fixes: 2a3d923 ("RDMA/hns: Replace magic numbers with #defines")
Fixes: 82e620d ("RDMA/hns: Modify the data structure of hns_roce_av")
Fixes: 8254746 ("IB/hns: Implement the add_gid/del_gid and optimize the GIDs management")
Fixes: 21b97f5 ("RDMA/hns: Fixup qp release bug")
