net/mlx5: DR, Remove mr_addr rkey from struct mlx5dr_icm_chunk
Reduce memory footprint by removing mr_addr and rkey from
mlx5_dr_icm_chunk.
1. mr_addr is calculated by mlx5dr_icm_pool_get_chunk_mr_addr()
2. rkey is calculated by mlx5dr_icm_pool_get_chunk_rkey()
The two new functions are very lightweight and straightforward.
Reduce 8 bytes from struct mlx5_dr_icm_chunk, its current size is
72 bytes.
