IB/mlx5: Don't mangle the mr->pd inside the rereg callback
The rereg protocol expects the core code to change mr->pd and synchronize
that change with the atomics and syncs. The driver should not touch it.
mlx5 needed to update it in umr_rereg_pas() because
mlx5r_umr_update_mr_pas() required the updated mr->pd to build the
UMR.
Simply switch mlx5r_umr_update_mr_pas() to use the pdn directly from
the new pd and remove the mr->pd update.
