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. Signed-off-by: Haggai Eran <haggaie@mellanox.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
