IB/mlx5: Add MR to radix tree in reg_mr_callback
For memory regions that are allocated using reg_umr, the suffix of
mlx5_core_create_mkey isn't being called. Instead the creation is
completed in a callback function (reg_mr_callback). This means that
these MRs aren't being added to the MR radix tree. Add them in the
callback.
